Question

What is the measure of ∠B?

Answer 1

When <C = 65
And, <A= 58

Answer 2

the sum of angles in a triangle is 180 degrees
so we will assign the uknown angle as "X"

65+58+x=180
133+x=180
x=180-133
x=47

47 degrees is your answer :P

Answer 3

\[\triangle = 180° = \angle_A+\angle_B+\angle_C\]
