Question

The vertical angle is an isosceles traingle is 80degree. Find measurment of its base angles.​​

Answer 1

Answer:

2x+80=180

2x=180-80=100

2x=100

x=100/2

x=50

Step-by-step explanation:

Answer 2

Answer:

Vertical angle = 80°

Let the base angles be x (base angles of isosceles triangle are equal)

A.T.Q

x+x+80° = 180° (Angle Sum Property)

2x+80° = 180°

2x = 180-80

2x = 100°

x = 100/2

x = 50°
