Question

Please explain how to do this im confused

Answer 1

70° & 70°

Explanation:

These angles are known as corresponding angles. This means they are congruent.

23x + 1 = 4 + 22x

23x + 1 - 22x = 4 + 22x - 22x

x + 1 = 4

x + 1 - 1 = 4 - 1

x = 3

Substitute the value for the variable.

23(3) + 1 = 70

4 + 22(3) = 70

Answer 2

70° , 70°

Explanation:

The 2 angles are corresponding and are congruent, then

23x + 1 = 4 + 22x ( subtract 22x from both sides )

x + 1 = 4 ( subtract 1 from both sides )

x = 3

Then the angles are

23x + 1 = 23(3) + 1 = 69 + 1 = 70°

4 + 22x = 4 + 22(3) = 4 + 66 = 70°
