Step-by-step explanation:
3x + 2x + 7x =180
5x + 7x = 180
12x = 180
x = 180 /12
x= 15
3x = 45
2x = 30
7x = 105

Step-by-step explanation:
let the angles of triangle be 3x° , 2x° and 7x°
a/q
3x+2x+7x = 180°
= 12x. = 180°
= X. = 180/12
=. X. = 15
Hence, angles of triangle = 3*x = 45°
,2*x = 30°
and 7*x = 105°
