Question

If angle of triangle are in the ratio 2:3:4 find the value of each angle

Answer 1

Step-by-step explanation:

let the angles of ∆be 2x ,3x and 4x

2x+3x+4x=180°

9x=180°

x=180°/9=20°

2x=2×20°=40°

3x=3×20°=60°

4x=4×20°=80°

angles of ∆ are 40°, 60° and 80°

Answer 2

Answer: fist angle=40°

Secend angle =60°

Third angle =80°

Step-by-step explanation:

Given (2:3:4) =sum of all angle of trangel

(2:3:4)=(a:b:c)

Sum of angle of trangel= 180

180= 2x+3x+4x (2:3:4)

180= 9x

X=180/9

X=20

(2×20)+(3×20)+(4×20) = 180

40+60+80=180

So

a= 40°

b= 60°

c= 80°
