Question

Find each of two equal anglesof an isosceles triangle whose third angle is 80 °​

Answer 1

Answer:

hey

Step-by-step explanation:

in a isoceles triangle

two angles are equal,let the angle be x

x+x+80=180

2x=180-80

2x=100

x=50

so each angle measure is 50°

Answer 2

Answer:

measure of angles of isosceles triangle is 180°

let the equal angle be x

thus,

80°+x+x=180°

80°+2x=180°

2x=180-80

2x=100°

x=100/2

x=50°

Hence the equal angles are 50°,50°
