(180-112)/2=34
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
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.
57.5 degrees
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
If that '56' has units of 'degrees', then the vertex angle is 68 degrees.
80 degrees
(180 - 38)/2 = 71 degrees (base angles of an isosceles triangle are congruent).
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.
If your "53" is in degrees, then the vertex angle is 74 degrees.
