Question

State the type of angles and solve for the given variable.

(3x+27)
129°
O Same Side Interior Angles; x = 34
o Corresponding Angles; x = 34
O Alternate Exterior Angles; x = 129
Alternate Interior Angles; x = 129

Answer 1

2nd option

Explanation:

The 2 angles are corresponding and are congruent , so

3x + 27 = 129 ( subtract 27 from both sides )

3x = 102 ( divide both sides by 3 )

x = 34
