Question

If angles of a triangle are in the ratio 2: 4:4, find the value of each angle and also percentage of each in the triangle​

Answer 1

let the angles be 2x,4x and 4x

Sum of all angles of ∆ = 180° ( Angle sum property of ∆ )

2x + 4x +4x = 180°

10x = 180°

x = 18°

angles :- 36°, 72° and 72°

_______________________________

Percentage of angle1 :- 36/180×100

= 20%

% of angle 2 :- 72/180*100

= 40%

% of angle 3 :- 40%
