Question

If the messure of angles of a ttriangle are in ratio 3;4;5 what is thee measure of smallest angle of triangle

Answer 1

Explanation:

let us take angle is X

3x + 4x +5x = 180 ( angle sum property)

12x = 180

X= 180/12

X= 15

3×15= 45

4×15= 60

5×15= 75

therefore , the measure of smallest angle is 45°
