Vertex angle = 180 - 2(62) = 56 degrees
57.5 degrees
The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
Vertex angle is 180-53-53 = 74 degrees

If your "53" is in degrees, then the vertex angle is 74 degrees.
80 degrees.

84 degrees
yes they do
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
Each base angle is 62.5 degrees
The two angles that are not the isosceles vertex are equal.
