2
20
O a 40 and b = 75
A
Which are the possible values of a and b?
a 50 and b = 50
O a 20 and b = 25
2
O a 35 and b = 90
bº
B

Answer 1

a = 50 and b = 50

Explanation:

Given CA = 2 and C = 2, we can say that triangle ABC is a isosceles triangle.

• In isosceles triangles, the corresponding angles of equal legs will also be congruent.

So,

m∠a = m∠b

And,

a = 50 and b = 50
