Respuesta :

The measure of the vertex angle of an isosceles triangle can be found by subtracting the measure of one of the base angles from 180 degrees.

In this case, one of the base angles measures 54 degrees.

To find the measure of the vertex angle, we subtract 54 degrees from 180 degrees:

180° - 54° = 126°

Therefore, the measure of the vertex angle of the isosceles triangle is 126°.

Answer:

C)72°

Step-by-step explanation:

In an isosceles triangle, the base angles are equal. If one base angle is 54 degrees, then the other base angle is also 54 degrees. The sum of all angles in a triangle is 180 degrees. To find the vertex angle, subtract the sum of the base angles from 180: \(180 - (54 + 54) = 72\) degrees. Therefore, the measure of the vertex angle is 72 degrees.
