Question

In
triangle ABC, angleA=45° and angleC=62°,
find the measure of Angle.
B​

Answer 1

Answer:

angle B =73 degree

Step-by-step explanation:

A+B+C=180

A=40

C=62

B=180-A+C

B=180-45+62

B=180-107

B=73

Answer 2

Answer:

73°

Step-by-step explanation:

In ∆ABC

angle A+angle B+angleC =180°

45°+angle B+62°=180°

angle B+107°=180°

angle B=180°-107°

=73°

So, angle B =73°
