Question

In a triangle, the measure of the first angle is twice as much as the second angle. The measure of the third angle is 76 degrees more than the measure of the second angle. Use the fact that the sum of the measures of the three angles of a triangle is 180 degrees to find the measure of each angle

Answer 1

Convert all the angles in terms of second angle, then find the second angle.

Answer 2

suppose the second angle is x so 2x+x+(x+76)=180>>4x=104>>x=26>>second angle and the first angle is twice of this angle, third angle is 26+76
