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

First angle: _____

Second angle: _____

Third angle ______

Respuesta :

let the first angle be a

then

second angle= 68+a

third angle=2a

we know

a+b+c=180 [sum of interior angle of triangle is 180]

a+68+a+2a=180

4a=180-68

a=28

Hence

first angle=28

second angle = 96

third angle =56
