Question

if one of the angles of a triangle is 650 and the other two angles are in the ratio of 2 : 3, find the other two angles

Answer 1

sum of all angles of a triangle=180°
let the angles be 2x and 3x and their sum 5x
2x+3x+65°=180°
5x+65°=180
5x=180-65°
5x=115°
x=115/5
x=23

Answer 2

Let, the other angles are 2x and 3x.
and one angle is 65.
thus , 2x + 3x + 65=180
5x=115.
x=23.
hence, other angles are 2x=46 and 3x =92.
