Question

Some isosceles triangle are drawn below. In each, one angle is given. Find the other angles
40°and30°

Answer 1

Answer:

The other angle of the triangle is 110°

Step-by-step explanation:

Given-

In triangle ABC, A= 40°, B= 30°

To find- C=?

Solution-

Triangle ABC is an isosceles triangle

Therefore, by issocles triangle theorem,

A+B+C= 180°

40°+30°+C=180°

70°+ C= 180°

C= 180°-70°

C=110°
