Question

I need hellpp i need to know what the angle is and what x is​

Answer 1

x = 7.

Angle = 70 degrees.

Explanation:

These 2 angles are exterior alternate angles and so they are equal.

So 9x + 7 = 10x

Subtract 7 from both sides:

9x + 7 - 7 = 10x - 7

9x = 10x - 7

Subtract 10x from both sides:

9x - 10x = 10x -10x - 7

-x = -7

x = 7

The measure of the angle = 10x

= 10*7

= 70 degrees.

Answer 2

x = 7

Explanation:

The 2 marked angles are Alternate exterior angles ( they are outside the parallel lines ) and are congruent, that is

10x = 9x + 7 ( subtract 9x from both sides )

x = 7
