Question

Use the Triangle Angle Sum Theorem to find the measure of the angle on point C.
(1 point)

Answer 1

m∠4 = 133°

Explanation:

Given m∠7 = 37°

Since m∠7 ≅ m∠6 [Vertically opposite angles]

and m∠6 + m∠4 = 180° [Sum of interior angles formed by parallel lines l, m and transverse.]

Therefore, 47°+ m∠4 = 180°

m∠4 = 180 - 47

= 133°
