Question

Determine the measure of the angle labeled (4x+7)°.

Answer 1

Answer:

  39°

Step-by-step explanation:

It is the same measure as the one labeled 6x-9, since these are vertical angles.

  4x +7 = 6x -9

  16 = 2x . . . . . . . . add 9-4x

  8 = x

  4x+7 = 4(8) +7 = 39

The angle is 39°.

Answer 2

Answer:

32

Step-by-step explanation:

First, combine like terms

4x+7=6x-9

     +9     +9

4x+16=-9

     -16   -16

Then divide by four to isolate x

4x=-25

x=-6.25

Plug in X to get the angle measure .
