Question

the vertical angle of an isoscales triangle is 100°, find its base angles.​

Answer 1

Answer:

this also called isosceles triangle two sides are equal and one side are different is called isosceles triangle

Answer 2

Answer:

40

Step-by-step explanation:

since the triangle is isoceles, the base angles are equal.

(angles opposite to equal sides are equal).

let one base angle be x

therefore another base angle also becomes x

100+x+x=180(angle sum property of a triangle)

100+2x=180

2x=180-100

2x=80

x=80/2

x=40

therefore the base angles are 40°
