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°
