Angle A is 54°

Angle b is x

Angle C is 74°

Find the angle of angle b in a triangle?


A) 50°

B) 52°

C) 60°

D) 57°

Answer 1

Explanation:

step 1. so ABC is a triangle.

step 2. interior angles of a triangle add up to 180°

step 3. <A + <B + <C = 180°

step 4. 54 + <B + 74 = 180°

step 5. <B = 52°.
