Question

16. In an isosceles triangle, the base angles are equal and the vertex angle is 80°. Find the
measure of the base angles.​

Answer 1

Answer:

in isosceles triangle a,b,c

Step-by-step explanation:

A=B

C=80

A+B+C=180

A+A+80=180

2A=180-80

A=100/2

A=50=B

HENCE, BASE ANGLES IS 50 DEGREE EACH

Answer 2

Answer:

let the base angles be x°

according to the question

x+x+80°=180°

2x+80°=180°

2x=180°-80°

2x=100°

x=50°
