Question

One Angle in a Triangle is 65° and the Difference between the Other Two is 20°. Find the Missing Angles. PLEASE SHOW THE STEPS TOO

Answer 1

Answer:

Angles A +B +C=180 eqn 1

B-C=20

B=C+20

Putting this value in eqn 1

A+C+20+C=180

65+2C+20=180(A=65)

2C+85=180

2C=180-85

2C=95

C=47.5

B-C=20

B=67.5
