Question

In an isosceles triangle each equal angle is twice the vertex angle. What is the measure of each equal angle

Answer 1

Answer:

The measure of each equal angle is 72°.

Step-by-step explanation:

The sum of all angles of a triangle is 180°.

It is provided that the equal angles of an isosceles triangle is twice the vertex angle.

Let the angles be 2x, 2x  and x.

Compute the measure of x as follows:

$2x+2x+x=180^{o}\\5x=180^{o}\\x=36^{o}$

The three angles are:

x = 36°

2x = 2 × 36° = 72°

2x = 2 × 36° = 72°

Thus, the measure of each equal angle is 72°.
