If h is an angle bisector of the given isosceles triangle, what is the measure of ∠a if ∠c = 55°?

a) 35°

b) 55°

c) 70°

d) 105°

A) 35°

Step-by-step explanation:

In the given picture , we have an isosceles triangle , in which h is an angle bisector , divide an angle into two parts named as ∠a and ∠a.

∠c = 55°

We know that the angles opposite to the equal sides of an isosceles triangle are equal.

By angle sum property , we have

 [Divide both sides by 2]

Hence, the correct answer is A) 35° .

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

d. corresponding side lengths in similar triangles are proportional in length.
