Question

Find m A)10
B)70
C)110
D)170

Answer 1

We know that : Vertically Opposite Angles of Two Intersecting Lines are Equal.

Here : The Pair of Vertically Opposite Angles are (2x + 50)° and (7x)°

⇒ (2x + 50)° = (7x)°

⇒ (7x)° - (2x)° = 50°

⇒ (5x)° = 50°

⇒ x = 10°

⇒ m∠AEB = (2x + 50)° = 2(10°) + 50° = (20° + 50°) = 70°

Option B is the Answer
