Answer:

[tex]\huge\boxed{\sf L = 78\°}[/tex]

Step-by-step explanation:

Exterior angle of L = 5x + 12

M = 3x - 2

N = 50

So, the exterior angle that is adjacent to L is equal to the sum of non-adjacent sides (M and N) of the triangle.

Here,

Exterior angle of L = M + N

5x + 12 = 3x - 2 + 50

5x + 12 = 3x + 48

Subtract 12 to both sides

5x = 3x + 48 - 12

5x - 3x = 36

2x = 36

Divide 2 to both sides

x = 18

So,

= 3x - 2

= 3 (18) - 2

= 54 - 2

= 52°

Now,

We know that,

L + M + N = 180°

L + 52 + 50 = 180

L + 102 = 180

Subtract 102 to both sides

L = 180 - 102

L = 78°

If the statement is "The difference of four times a number and seven is ten times the number." then an algebraic equation is 4x-7= 10+x and the solution is -7/6.

Given the statement "The difference of four times a number and seven is ten times the number." We have to translate the statement in an algebraic equation and then solve it.

Let, the number be x.

This difference of four times a number and seven is 4x-7 and ten times the number is 10x

According to the question, the equation is,4x-7= 10x

4x-7=10x

6x=-7

x=-7/6

Answer:

y = 139

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

110° is an exterior angle of the triangle , then

3x + 2x - 5 = 110

5x - 5 = 110 ( add 5 to both sides )

5x = 115 ( divide both sides by 5 )

x = 23

then

2x - 5 = 2(23) - 5 = 46 - 5 = 41

y and 2x - 5 are a linear pair and sum to 180° , so

y = 180 - 41 = 139

Answer:

I got 139

Someone correct me if I'm wrong.

Step-by-step explanation:

(2x-5) + 3x + 70 = 180

Collect liketerms. Take away 70 from both sides and add 5.

5x=115

x=23

2(23) -5 = 41

180-41 = 139

y = 139

It would be 5 because three quarters of 20 would be 15, and 5 would be the remainder.

1. In terms of x and y, the height of the tree is [tex]h = y \times tan \ t^\circ[/tex] and[tex]h = x \times tan \ s^\circ[/tex]

2. The height of the tree is 6.71 meters

From the question, we are to determine the height of the tree in terms of x and y

Using SOH CAH TOA, we can write that

[tex]tan \ t^\circ =\frac{h}{y}[/tex]

∴ [tex]h = y \times tan \ t^\circ[/tex]

Also,

[tex]tan \ s^\circ =\frac{h}{x}[/tex]

∴ [tex]h = x \times tan \ s^\circ[/tex]

2. If m∠t = 40° and y = 8 meters,

Then, the height of the tree

h = 8 × tan40°

h = 6.71 meters

Hence, the height of the tree is 6.71 meters

The general form and the standard form of the graph equation are 13x - 8y = 17 and 13x - 8y - 17 = 0 respectively

From the graph, we have the following points

(x,y) = (5,6) and (-3,-7)

Start by calculating the slope:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

This gives

[tex]m = \frac{-7 - 6}{-3 - 5}[/tex]

Evaluate the differences

[tex]m = \frac{-13}{-8}[/tex]

Evaluate the quotient

[tex]m = \frac{13}{8}[/tex]

The equation is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

This gives

[tex]y = \frac{13}8(x - 5) + 6[/tex]

Multiply through by 8

8y = 13(x - 5) + 48

Open the bracket

8y = 13x - 65 + 48

Evaluate the like terms

8y = 13x - 17

Subtract 13x from both sides

-13x + 8y = -17

Multiply through by -1

13x - 8y = 17 ---- this represents the standard form

Subtract 17 from both sides

13x - 8y - 17 = 0 --- this represents the general form

Hence, the general form and the standard form of the graph equation are 13x - 8y = 17 and 13x - 8y - 17 = 0 respectively

On the other hand, we can observe that the subset representing "has leaves" lie inside another subset which represents "trees," which contradicts the given statement "If it is a tree, then it has leaves."

Yes it is what is the question you are answering and it's 90 degree

Answer:

yes line is a tangent to the circle

Step-by-step explanation:

the angle between a tangent and the radius of a circle is 90°

If the triangle is right then the line touching the circle is a tangent.

using the converse of Pythagoras' identity

if the square on the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right

longest side = 65 and 65² = 4225

56² + 33² = 3136 + 1089 = 4225

then the triangle is right and the line touching the circle is a tangent

You buy 3 shirts and 1 pair of pants for $32. Your friend buys 2 shirts and 3 pairs of pants for $40. How much did each item cost?

First let’s define a shirt as X and pants as Y!

In the first scenario, the equation will be 3X + Y =$32

In the second scenario, the equation will be 2X + 3Y = $40  

Now because we have two different variables (X & Y) let’s solve for one of them (Ex: Y) to simplify the equations!

3X + Y= $32—> subtract 3X on both sides of the equation  

-3X.        - 3X

Net result: Y= 32- 3X

Now we can insert this into the second equation 2X + 3Y = $40 in order to solve for X variable  

2X + 3(32-3X) = $40

2X + 96 - 9X = $40 —> simplify the equation  

-7X + 96 = $40 —> substrate 96 from both sides  

-7X = -56 —> divide both sides by -7  

X= 8  

Now reinsert 8= X into 3X + Y = $32

3(8) + Y = $32

24+ Y = $32 —> substract 24 from both sides

y = 8

Little tick marks are used to show that two sides are the same length (congruent).  You can use just one tick mark, two or three, or more -- just as long as you use the same number on sides that are equal.

Answer: x = 8 and y = 19

Explanation:

Triangle MLN ≅Triangle SRT

Therefore, each angle and side measure of one triangle are equal to the corresponding angle and side of the other triangle.

<M ≅ <S

<S= 93 (Given)

<M=93

<N=63 (Given)

Line segment ML ≅ Line segment SR

Line segment ML = 43

Line segment SR = 3x + y

Now, we need to find the values of x and y.

43 = 3x + y

<M+<N+<L=180 (Interior angles measure of a triangle is always 180)

93+63+z=180

156+z=180

z= 24

24 is the measure of <R.

<R=3x

24=3x

x=8

Now if we plug in the 8, the value of x, into our equation above,

43=3x+y

43=3(8)+y

43=24+y

43-24=y

19=y
