Angle sum Theory 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°

Step-by-step 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°.

the answer for your question b is 52

NS:

kh (kh + 16) = 152

Iks

2 + 16x - 225 = 0

(kh + 25) (kh - 9) = 0

kh = 9

u

2 = 16 ⋅ 9

u

2 = 144

u = 12
