Question

the angles formed by the two equal sides of isoceles triangle is 100 .find uts base angles.​

Answer 1

Answer:

40 degrees each.

Step-by-step explanation:

In an isosceles triangle, base angles are equal.

100 + x + x = 180

2x = 80

Answer 2

Answer:

let Abc is an isosceles∆

Ab=Bc and angle A= 100

angle B = anble C

by angle sum. property of triangle

a+b+c= 180*

b+b+100=180* ( angle b = angle c)

2b +100=180*

2b=180-100

2b=80

b=80/2

b= 40

b=c=40
