Question

In a triangle ABC, angle B =35° and angle C=60° then
a. angle A=80°
b. angle A=85° c. angle A= 120°.
d. angle A=145°​

Answer 1

The sum of triangle is 180

so,A+B+C=180

A+35+60=180

A=180-95

A=85

I hope my answer will help you

Answer 2

Step-by-step explanation:

In a triangle angle B=35°

Angle C=60°

Total triangle = 180°

So, 35°+60° =95°

So angle A=180° - 95°

=85°

Hence,option a is the correct answer.
