Question

Find mangleB in the triangle ABC if mangleA = 34° and mangleC = 117°.

Answer 1

Answer:

given

Step-by-step explanation:

in a triangle ABC

angleA=35°

angleC=117°

let the angleB=x (sum of the three angles in a triangle is 180°

35°+117°+x°=180°

152°+x°=180°

x°=180°-152°

x°=28°

thus the angleB is 28°
