Question

Two angles of a triangle are equal and its third angle is double of the equal angle. Find the measure of the three angles of the triangle.

Answer 1

equal angles are 45 and 45

third one is 90

Answer 2

45°, 45° , 90 °

Step-by-step explanation:

We know that sum of all the angles of a triangle is = 180°

Here two angles are equal , let them be = x + x

Another angle is double of the equal angles - 2*x = 2x

So therefore x is .-

x+x+2x = 180°

4x = 180°

x = 180/4

x = 45 °

So two equal angles are 45° each and third is 2 * 45 = 90 °
