Answer 1

Here is what I am thinking about this problem:

Answer 2

Altitudes drawn to the legs of an isosceles triangle from the vertices of the base of the isosceles triangle are congruent. So,

Answer 3

one of the altitudes must be drawn from the vertex angle of the triangle given that the altitudes have measure 20 and 30.
