Question

Given the triangle with angle a being 53° angle C being 58° what is angle B

Answer 1

Answer:

69°

Step-by-step explanation:

A + B + C = 180°

53° + B + 58° = 180°

B + 111° = 180°

B = 69°

Answer 2

Sum measure interior angle = (n-2)180 ; n is the no.of sides

=(3-2)180

= 180°

53+59+x = 180

111+x = 180

x = 180-111

x = 69°

Angle B is 69°
