Question

The

second angle of a triangle is two times the first angle. The third
angle of the triangle is 68 degrees more than the first angle. Find
each angle of the triangle.

Answer 1

x = the measurement in degrees of the 1st angle

2x= the measurement in degrees of the 2nd angle

x+68 the degree measure of the 3rd angle

the sum of the angles of a triangle = 180°

x+2x+x+68=180

4x=180-68

x=28

value of x (in degrees) 28

1er angle = 28°

second angle = 56°

third angle = 96°
