Answer 1

Equation:x+70=8x and both angles measure 80 degrees.

Explanation:

Equation:x+70=8x

That is because vertical angles are congruent.

x+70=8x

-x -x

70=7x

x=10

Both angles measure 80 degrees.

Answer 2

Equation: 8x = x + 70

x = 10

Both angles measure 80°

—
Work:

the two angles are vertical angles, meaning that they are equal to each other, hence the equation will be this:

8x = x + 70

To solve, subtract x on both sides

7x = 70

Divide 7 on both sides to isolate the x

x = 10


Now, to find both of the angles measurement, plug in 10 for x.

10 + 70 = 80

8(10) = 80
