If the 58°-angle is one of the base angles, then the vertex angle is 64°.If the 58°-angle is the vertex angle, then the vertex angle is 58°.
180 - twice 42
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.
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
If the 58°-angle is one of the base angles, then the vertex angle is 64°.If the 58°-angle is the vertex angle, then the vertex angle is 58°.
80 degrees
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
If each base angle is 56°, then the vertex angle is 68°.If both base angles combined total 56°, then the vertex angle is 124°.
Since you know one base angle is 54 then the other base angle is also 54 making a total of 108. Since a triangle is 180, your vertex angle is 72.

90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
If your "53" is in degrees, then the vertex angle is 74 degrees.
20 degrees
