Question

How do you solve this equation?

Answer 1

Answer:

b=85º

a=20º

Step-by-step explanation:

Angle B is supplementary with the 45º and the 50º angle, therefore the sum of the three angles must be 180

45+b+50=180

95+b=180

b=85º

Angle A, Angle B, and the 75º angle must also add up to 180

85+75+a=180

160+a=180

a=20º
