The answer is a because the last angle will be 70 since it is an isosceles which means that all the angles are acute therefore the answer is acute isosceles

Answer:

A.

Explanation:

The third angle is 180 - 2*55 = 70 degrees.

So with 2 sides and 2 angles equal it is an acute isosceles triangle.
