Question

if the measure of angle of a triangle are in the ratio:3;4:5what is the measure of the smalleast angle of the 30°45°60°90°​

Answer 1

Answer:

let the angles be 3x,4x,5x

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

12x=180

x= 15

the measure of smallest angle is (3×15)=45°

Answer 2

⭐Given:

• Ratio of the angles of a triangle are in the ratio 3:4:5.

⭐To Find:

• Measure of the smaller angle of a triangle=?

⭐Solution:

Let here the common multiple be x.

Therefore,

3x+4x+5x=180°..........(Sum of all angles of a triangle are 180°)

: . 12x=180°

: . x=180/12

: . x=15

Therefore,

The smaller angle =3x=45°
