Answer:
The value of x is 117° by using Alternative interior angle theorem
Step-by-step explanation:
Alternative interior angle theorem: It states that the angles made by transverse between two parallel lines are congruent.
as in figure
Angle A = 42°
Angle B = 108°
Angle C = x
Angle D = 51°
draw two parallel lines passing through B and C .
According to Alternative interior angle theorem angle B is written as 42° + 66°
and angle C is written as x1 + x2 .
Now x1 = 51° as x1 and D are alternative angles
And similarly x2 = 66°
As x = x1 + x2
Therefore x = 51° + 66° = 117°
The value of x is 117°

Linear equation: 1/4a+1/3a+8=22
Answers
Answer:
a=24
Step-by-step explanation:
Start by subtracting 8 from both sides giving:
1/4a+1/3a=14
Then find a common denominator between the two a terms which is 12 giving:
3/12a+4/12a=14
Combine the two terms:
7/12a=14
Then divide by 7/12 giving you a=24
Mario is setting up a new tent during a camping trip. The tent came with 7 feet of rope. The instructions are to use 34.5 inches of the rope to tie a tarp on top of the tent. then, the remaining rope should be cut into 8 1/4 - inch sections to tie the tent to stakes in the ground. Mario will use all of the rope as instructed. write and solve n equation to determine the number of 8 1/4 - inch sections of rope Mario can cut from the rope
Answers
An equation is formed of two equal expressions. The number of sections that Mario can cut from the rope is 6.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of 8 1/4 - inch sections of rope Mario can cut from the rope be x.
Since the total length of the rope is 7 feet, which is equal to 84 inches(1 foot=12 inches), the instructions are to use 34.5 inches of the rope to tie a tarp on top of the tent. Therefore, the rope for the 8 1/4 inches section is,
Rope left = 84 inches - 34.5 inches
Since the length of a single section is 8 1/4 inches(8.25 inches), therefore the number of sections that can be made from the remaining section is,
The number of sections, n = Rope left/8.25 inches
= (84 -34.5)inches /8.25 inches
= 6
Hence, the number of sections that Mario can cut from the rope is 6.

Answers
Answer:
In the given Triangle problem, the three options are:
1. m∠5 + m∠6 = 180°
2. ∠2+ ∠3 = ∠6
3. m∠2 + m∠3 + m∠5 = 180°
Step-by-step explanation:
Concept: Consider Δ ABC with Exterior angles ∠1, ∠4 and ∠6.
Use the Exterior angle Property of Triangle which says that an exterior angle of a triangle is equal to the sum of the opposite interior angles.
For Exterior angle ∠1 we have:
∠1 = ∠5 + ∠3
Similarly, for Exterior ∠4 we have:
∠4 = ∠5 + ∠2
Similarly, for Exterior ∠6 we have:
∠6 = ∠2 + ∠3
Now, use the Triangle Sum Property which states that in a triangle sum of the measures of angles is equal to 180°
m∠2 + m∠3 + m∠5 = 180°
Linear Pair:
The measure of a straight angle is 180°, so a linear pair of angles must add up to 180°.
m∠5 + m∠6 = 180°

a)
[tex]y=2x^{2} +12x +1[/tex]
[tex]y = 2[(x^{2} + 6x)] + 1[/tex] ( taking common)
[tex]y = 2[(x+3)^{2} - 9] + 1[/tex] ( adding and subtracting 9 to make a square term

Step-by-step solutionLinear equations with one unknown_____________________________________
1. Group all constants on the right side of the equation
[tex]\frac{2}{3}\cdot x+\frac{5}{6}=\frac{10}{3}[/tex]
Subtract [tex]5/6[/tex] from both sides:
[tex]\frac{2}{3}x+\frac{5}{6}-\frac{5}{6}=\frac{10}{3}-\frac{5}{6}[/tex]
Combine the fractions:
[tex]\frac{2}{3}\cdot x+\frac{5-5}{6}=\frac{10}{3}-\frac{5}{6}[/tex]
Combine the numerators:
[tex]\frac{2}{3}\cdot x+\frac{0}{6}=\frac{10}{3}-\frac{5}{6}[/tex]
Reduce the zero numerator:
[tex]\frac{2}{3}\cdot x+0=\frac{10}{3}-\frac{5}{6}[/tex]
Simplify the arithmetic:
[tex]\frac{2}{3}\cdot x=\frac{10}{3}-\frac{5}{6}[/tex]
Find the lowest common denominator:
[tex]\frac{2}{3}\cdot x=\frac{10\cdot 2}{3\cdot 2}+\frac{-5}{6}[/tex]
Multiply the denominators:
[tex]\frac{2}{3}\cdot x=\frac{10\cdot 2}{6}+\frac{-5}{6}[/tex]
Multiply the numerators:
[tex]\frac{2}{3}\cdot x=\frac{20}{6}+\frac{-5}{6}[/tex]
Combine the fractions:
[tex]\frac{2}{3}\cdot x=\frac{20-5}{6}[/tex]
Combine the numerators:
[tex]\frac{2}{3}\cdot x=\frac{15}{6}[/tex]
Find the greatest common factor of the numerator and denominator:
[tex]\frac{2}{3}\cdot x=\frac{5\cdot 3}{2\cdot 3}[/tex]
Factor out and cancel the greatest common factor:
[tex]\frac{2}{3}\cdot x=\frac{5}{2}[/tex]
2. Isolate the x
[tex]\frac{2}{3}\cdot x=\frac{5}{2}[/tex]
Multiply both sides by inverse fraction 3/2:
[tex]\frac{2}{3}x\cdot \frac{3}{2}=\frac{5}{2}\cdot \frac{3}{2}[/tex]

Step-by-step explanation:
Interior angles of hexagon = 120 degrees ....now look at the Right 1/2 of the hexagon... see illustration....this is a trapezoid...
One base is 10 units
the other labelled 'base' is
10 cos 60 + 10 cos 60 + 10 = 20 units
the height of this trapezoid is 10 sin 60 = 10 * sqrt(3)/2 = 5 sqrt(3)
the area of this trapezoid is then 1/2 ( 10+ 20) * 5 sqrt (3) = 75 sqrt 3
there are TWO of these trapezoids in the hexagon so total area is then

the rec room is Amado one large rectangle from
(5, 6) to (8, -7).
I am basing the rest in this.
for the area calculations, please consider that the area of a rectangle is length × width, and the area of a triangle is half of the rectangle it splits in half with its baseline (as diagonal).
A)
area 1 =
rectangle (-8, 8) to (-5, 3)
plus
half of the rectangle (-5, 8) to (-3, 3)
3×5 + 1/2 × 2×5 = 3×5 + 1×5 = 15 + 5 = 20 yd²
area 2 =
half of the rectangle (-5, 8) to (-3, 3)
plus

1/2 × 2×5 + 3×5 = 20 yd²
area 3 = area 4 =

Answers
Answer:
30
Step-by-step explanation:
P=2(b+h)=2·(10+5)=30
Step-by-Step Solution:
We know, Base = Length and Height = Breadth of the Rectangle.
Length (l) = 10
Breadth (b) = 5
Perimeter of the Rectangle = 2(l + b)
Therefore,

= 2(10 + 5)
= 2(15)
= 2 * 15
=> 30
Perimeter of the Rectangle = 30
