Question

One angle of a triangle is 3 times the second the third angle is 72 degrees

Answer 1

Here you have x + 3x + 72 = 180. By isolating the variable by dividing on both sides, the answer is x = 27

Answer 2

18, 54, 108

Explanation:

Let the first angle is ‘x’

Second angle =3x

Third angle=2(3x)=6x

Sum of the three angles of a triangle =180 degrees

x+3x+6x=180

x=18

The first angle is 18,second angle is (3*18)=54.third angle is (6*18)=108

The angles are 18,54 and 108 degrees
