Question

If the angles of triangle are in the ratio 2:3:4 then the difference between greater and the smallest angle is _

Answer 1

let thd angles be 2x,3x4x
so 9x=180°
x=20°
so largest angle 4x=80°
smallest angle 2x=40°
so diffremce is 40°

Answer 2

Sum of the angles of triangle =180
Ratios of angles=2:3:4
Sum of the ratio=9
First angle =180÷9×2=40 degree
scenod angle=180÷9×3=60degree
third angle=180÷9×4=80degree
Difference between largest and smallest angle is 40
(80-40=40)
