Question

16.In an isosceles triangle, the base angles are equal, and the vertex angle is 80 degrees.

Find the measure of the base angles.

​

Answer 1

Answer:

50, 50

Step-by-step explanation:

let base angle be X

some of angles

X+X+80=180

2X=180-80

2X=100

X=50

Answer 2

Answer:

50°

Step-by-step explanation:

Given

In isosceles triangle ABC,

∠A=∠B=x

∠C=80°

By angle sum property,

∠A+∠B+ ∠C=180°

x+x+80°=180°

2x+80°=180°

2x=100°

x=100°/2

x=50°

Therefore, ∠A=∠C=x=50°
