Question

In a triangle,sum of two angle is 100° and their difference is 30°. Find all the angles.​

Answer 1

Answer:

A = 65 B = 35 C = 80

Step-by-step explanation:

Given: A+B = 100°

A-B = 30°

Adding both

A+B+A-B = 100+30

2A = 130

A = 65°

Now,

65+B = 100°

B = 100- 65

B = 35°

Now by using angle sum property of a ∆

A+B+C = 180°

100+ C = 180°

C = 80°
