The both have the same x coordinate so vertical would be correct.

∠A and ∠B are vertical angles. If ∠A=8x+14 and ∠B=2x+50, what is m∠B?

Maslowich

Answer:

∠B = 62°

Step-by-step explanation:

Because ∠A and ∠B are vertical angles they are equal hence we can write

∠A = ∠B

8x + 14 = 2x + 50

Now we have to solve for x

To do so, subtract 2x on both sides of the equation:

6x + 14 = 50

Now, subtract 14 on both sides of the equation

6x = 36

Now, divide 6 on both sides of the equation

x = 6

To find m∠B you have to you have to plug in x = 6 back into the ∠B equation

∠B = 2(6) + 50

∠B = 62°

Could someone give me an answer and explain how you got it ?

tankabanditka [31]

Answer:

A (9, 3)

Step-by-step explanation:

First the point is rotated 90° counterclockwise about the origin. To do that transformation: (x, y) → (-y, x).

So S(-3, -5) becomes S'(5, -3).

Next, the point is translated +4 units in the x direction and +6 units in the y direction.

So S'(5, -3) becomes S"(9, 3).

Graph a triangle on the coordinate plane. Choose 1 transformation (reflection, rotation,

BlackZzzverrR [31]

Answer:

The answer in the procedure

Step-by-step explanation:

we have the right triangle ABC

The pre-image coordinates are

$A(0,0),B(0,3),C(4,0)$

The transformation to use is the translation

The rule of the translation is

$(x,y)-----> (x+10,y)$

That means----> The translation is 10 units to the right

The image coordinates are

Applying the rule of the translation

$A'(0+10,0)=A'(10,0)$

$B'(0+10,3)=B'(10,3)$

$C'(4+10,0)=C'(14,0)$

using a graphing tool

see the attached figure
