In angle ABC, angle A=47, and angle C=41. What's angle B?

Question

Geometry word problems

Answer 1

In a triangle, the sum of the angles is 180°

 

In ΔABC, ∠A = 47° and ∠C = 41°, so ∠B = 180 - 47 - 41 = 92°

Answer 2

In all triangles the three angles sum to 180°.

 

m∠B = 180 - m∠A - m∠c

m∠B = 180 - 47 - 41

m∠B = 92°
