Question

The angle formed by the two equal sides of an isosceles triangle is 100 degree. Find its base angles.
Who will give correct answer of this question then I will mark him brainliest and I will give him 100 thanks​

Answer 1

Answer:

Step-by-step explanation:

base angles are 40 degree each.

subtract 100 from 180 you will get 80 degree. we know that two equal sides of isosceles triangle have opposite angles equal.

Answer 2

Answer:

Baase angles are 40°

Step-by-step explanation:

In an isosceles triangle base angles are equal... (1)

So, sum of angles of triangle is 180°

Assuming base angles are B1 and B2

As per (1), base angles are equal so B1=B2

Now,

100° +B1 + B2 =180°

100° + B1 +B1 = 180°

2(B2) = 180°-100°

B2 = 80°/2

B2 = 40°

Hence, B1 = 40°
