Question

If each of the two equal angles of an isosceles triangle is twice the third angle, the measure of the third angle is

Answer 1

Let the third angle be x
And the two equal angles be 2x
Now as we know the sum of all angles of a triangle is 180
2x+2x +x= 180
Or, 5x=180
Or, x = 180/5
Or, x=36
Therefore the measure of 3rd angle is 36 units
