Question

The three angles of a triangle are in the ratio 2:3:5. Find the measure of each angle. Classify the triangle.

Answer 1

Answer:

Let the number be x,

By the problem,

2x+3x+5x=180

= 10x=180

= x=180/10

= x=18°

2x=18×2=36°

3x=18×3=54°

5x=18×5=90°

It is a right angle triangle.

HOPE IT HELPS ✌️✌️✌️.

Answer 2

Answer:

Ratio =2:3:5

Let x to ratio=2x+3x+5x

Sum of angle in triangle =180

2x+3x+5x=180

10x=180

X=180/10

X=18

First angle=2x =2*18=36

Second angle =3*18=54

Third angle=5*18=90
