Question

if the angles of a triangle are triangle are in the ratio 2:3:5. find the smallest angle​

Answer 1

Answer:

36 degrees is the smallest angle!

Answer 2

let the ratios be 2x, 3x and 5x

sum of angles in a triangle =180°

thus,

2x+3x+5x=180°

10x=180°

x=180/10

x=18°

therefore,

2x=2×18

=36°

3x=3×18

=54°

5x=5×18

=90°

thus, 36° is the smallest angle
