Question

36. If vertex angle of isosceles triangle 1 poin
is 70. Find the base angles.
O a) 45
O b) 55
O c) 65
d) 75​

Answer 1

Answer:

If the vertex angle of a isosceles triangle is 70° then

Let both the base angles be x°( As both base angles are equal of isosceles triangle)

then we have,

=70°+x°+x°=180°

=2x°=110°

=x=55°

Hence, answer is (b) 55
