Answer» ONG>Answer: 80° Explanation- unknown angle = 180-sum of ANGLES ( Angle sum property of the triangle) =>180-70+30 (using BODMAS) =>180-100 unknown angle = 80° Since angle B = angle Q Angle B & Angle Q = 80° Pls mark this as brainliast

Answer» ONG>Answer:

80°

Explanation-

unknown angle = 180-sum of ANGLES ( Angle sum property of the triangle)

=>180-70+30

(using BODMAS)

=>180-100

unknown angle = 80°

Since angle B = angle Q

Angle B & Angle Q = 80°
