Question

find the angle of a triangle which are in ratio 4 ratio 3 ratio 2

Answer 1

Sum of all angles of triangle = 4x + 3x + 2x
180 = 9x
180÷9 = x
20 = x

Answer 2

Let the angles be 4x°, 3x° and 2x°.

We know that the sum of the angels of a triangle is 180°.

According to question,

4x°+3x°+2x°=180°
=> 9x° =180°
=> X° = 180°/9
=> X° = 20°

Hence, the angles are 4×20°=80°, 3×20°=60° and 2x=2×20°=40°.
