A right angle triangle is given.
We have to prove that measure of the segment that joins the vertex of the right angle in a right triangle to the midpoint of the hypotenuse is one-half the measure of the hypotenuse.
What is a triangle ?
A triangle is a 3-sided shape. There are three sides and three angles in every triangle, some of which may be the same.
As per the question ;
Let's assume P is the midpoint of the hypotenuse of the right angle △ABC and it is right angled at B. Also , D is the midpoint of AB.
Now ;
Draw a line parallel to BC from P meeting B at O and join PB.
Here ;
In △PAD and △PBD
∠PDA =∠PDB = 90°
and
PD = PD common)
AD = DB (As D is mid point of AB)
So ;
△ PAD ≅ PBD
by SAS rule
and
PA = 1/2 PB
Thus , we have proved that PA = 1/2 PB using the SAS rule or Side Angle Side rule.

The length of an inscribed angle is half the length of the central angle. The circumscribed angle's measure is 180 degrees less the central angle's measure.
What is the inscribed angle and the circumscribed angle?In geometry, an inscribed angle is the angle formed in the interior of a circle when two chords intersect on the circle. It is also the angle formed by two given points on a circle at a given point on the circle.
The length of an inscribed angle is half the length of the central angle. The circumscribed angle's measure is 180 degrees less the central angle's measure.
m ∠ABC = m ∠ABD + m ∠DBC (∠ Addition Postulate)
m ∠ABD = 1/2 m(arc AD)
m ∠DBC = 1/2 m(arc DC)
(The measure of an inscribed ∠ whose side is diameter is half the measure of the intercepted arc (Case 1)).
m ∠ABC = 1/2 m(arc AD) + 1/2 m(arc DC) (Substitution)
m ∠ABC = 1/2 [m(arc AD) + m(arc DC)] (Factor)
m(arc AD) + m(arc DC) = m(arc AC) (Arc Addition Postulate)
m ∠ABC = 1/2 m(arc AC) (Substitution)

Three personal watercraft vehicles launch from the same dock. The first vehicle leaves the dock traveling due northeast, while the second vehicle travels due northwest. Meanwhile, the third vehicle leaves the dock traveling due north.
The first and second vehicles stop about 300 yards from the dock, while the third stops about 212 yards from the dock.
(d) Write a coordinate proof to prove that the positions of all three watercrafts are approximately collinear and that the third watercraft is at the midpoint between the other two.
The line created by 1st and 2nd is making the same angle with 3rd so all three will be colinear and 3rd is the midpoint of 1st and 2nd.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given the condition making a graph as shown below,
Now in ΔAOC and ΔBOC, the angle x is the same.
Distance AO = BO and CO is common side.
So both triangles will be congruent.
Since all corresponding side of two congruent triangles is the same.
So,
AC = BC hence C will be the midpoint of A and B.
Hence "The line created by 1st and 2nd is making the same angle with 3rd so all three will be colinear and 3rd is the midpoint of 1st and 2nd".

For the given systems of equations, we have that:

19. The substitution method was used, as writing x as a function of y in the given equation was quite straight forward, as was replacing into the second equation to find y.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For item 17, the system is:
3x + 2y = 17.4x - 2y = 4.Adding the equations, we can eliminate y and solve for x, hence:
7x = 21
x = 3.
Then the solution for y is given as follows:
3x + 2y = 17
3(3) + 2y = 17
2y = 8
y = 4.
For item 18, the variables are given as follows:
Variable x: number of level I engineers.Variable y: number of level II engineers.The company has 8 engineers, hence:
x + y = 8 -> x = 8 - y.
The company can afford to pay a total of $472,000 to the engineers, hence, considering the salaries(in thousands of dollars) of each:
56x + 68y = 472.
We want to solve for y, hence, since x = 8 - y:
56x + 68y = 472.
56(8 - y) + 68y = 472.
12y = 24.
y = 2.
The company can afford to promote 2 engineers to level II.

I need to find out the quadrilateral of 78° k,L,N,M
Answer: ∠L = 102°
∠N = 78°
Step-by-step explanation:
Quadrilaterals can be classified into Parallelograms, Squares, Rectangles, and Rhombuses. Square, Rectangle, and Rhombus are also Parallelograms.
A quadrilateral is called a parallelogram, if both pairs of its opposite sides are parallel. AB ∥ DC and AD ∥ BC. So, ABCD is a parallelogram. A parallelogram having all sides equal, is called a rhombus.
Given data,
In □KLMN, side LM ∥ side KN, side KL ≅ side NM If ∠K = 78°
then find the measure of ∠L, and ∠N
side LM∥ side KN
Interior angles on the same side of the transversal are supplementary.
∠K + ∠L = 180°
78° + ∠L = 180°
∠L = 180° - 78°
∠L = 102°
Construction:
Draw LP ∥ MN
So, LM ∥ KN and LP ∥ MN
PLMN is a parallelogram
MN ≅ LP
Now MN = LP and MN = KL
LP = KL
∠LKP = ∠LPK = 78°
LP ∥ MN so,
∠MNP = ∠LPK = 78° (corresponding angles are equal)
∠L = 102°
∠N = 78°
Therefore,
∠L = 102°
∠N = 78°.

The solution of the given equation y/y+1 = 2/3 is calculated as (y = 2).
What is meant by cross multiplication?In cross-multiplication, the numerator of the first fraction is multiplied by the denominator of the second fraction, and the numerator of the second fraction is multiplied by the denominator of the first fraction.
Denominators are removed during cross multiplication. It's employed to make comparisons fraction sizes, solve proportional and percentage problems.A absent value or variable is common in proportion problems. After removing the denominators with cross multiplication, algebra skills are employed to solve again for missing variable. Percentage problems are solved in the same way that proportion problems are.Now, the given equation is as follows;
y/y+1 = 2/3
Cross-multiplying the values;
3y = 2(y + 1)
3 y = 2y + 2
Bring the variable on the single side and constants on the other.
3y - 2y = 2
y = 2
Therefore, the solution of the given equation y/y+1 = 2/3 is computed as (y = 2).

The simplification by combining like terms of 5v-3(2 -v) is 8v - 6.
According to the given question.
We have an expression5v - 3(2 - v).
As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same. when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.
Since, we have to combine the like terms of the given expression
5v - 3(2 - v).
Here 5v, and 3v both are the like terms.
So, we add coeffcients of v to simplify the given expression.
Therefore, the simplification of 5v -3 (2 -v ) is given by
5v - 3(2 - v)
= 5v - 6 + 3v
= 8v - 6
Hence, the simplification by combining like terms of 5v - 3(2 - v) is 8v - 6.

Find the area of the polygon.
The area of the polygon is what?
Answer:
Area = 792 m
Step-by-step explanation:
You can cut the polygon into 2 rectangles.
Subtracting 18 from 60 can give you the length of rectangle A, so 42 will be the new length for rectangle A.
Multiply 6 and 42 to get 252 for the area of rectangle A.
Multiply 18 and 30 to get 540 for the area of rectangle B.
(You multiply to find the area.)
Lastly you add both areas, 252 + 540, and the final result is:
