84 degrees

84 degrees

(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).

If a triangle is an isosceles triangle as well as being a right-angled triangle, the size of the two angles (that are not right angles) are 45 degrees.

You are an isosceles triangle.

In all triangles, the angles always measure up 180 degrees. In an isosceles triangle two of the angles are equal.

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.

40 degrees each

63 degrees

It is possible if neither of the angles in the triangle measures to 60 degrees
