Question

The vertical angle of an iscocles triangle is 80 degrees . find the base angle

Answer 1

Answer:

Step-by-step explanation:

Let the base be x° and x°

Vertical angle of an isosceles triangle =80°

So,

( x + x + 80)° = 180°

2x + 80 = 180

2x = 180 - 80

2x = 100

X = 100/2

X = 50

So,its base angles are 50° and 50°
