Question

One angle of an isosceles triangle is 100 degree find measure of oter two angles?

Answer 1

Step-by-step explanation:

one angle =100

let other angle be =x

another angle =x

=2x+100=180

=2x=180-100

=2x=80

=x=80/2

=x=40

other angles are 40,40

Answer 2

Answer:both angle will be of 40 degree

Step-by-step explanation:

Need to be logical

In every triangle , sum of all three angles is 180 degree

And in isoceles triangle any two sides are equal

I.e. in isoceles traingle any two angle will be also equal because if any two angles are equal then side in front of them will also be equal

Therefore suppose the value of both angle which are equal is x degree

And other angle is 100 degree

Then sum of three angle is 180 degree

So x+x+100 = 180

2x = 80

Hence x=40
