Question

The angles of a triangle are in ratio 5:4:3Find the measure of each angle​

Answer 1

Answer:

Step-by-step explanation:

Given ratio of angles in a triangle

are 5: 4: 3

Let First angle = 5x,

Second angle = 4x,

Third angle = 3x

5x+ 4 +3x = 180°

(Angle sum Property)

12x = 180°

x = 15°

First angle = 5x = 5 x 15 = 75°,

Second angle = 4r = 4 x 15 = 60",

Third angle = 3x =3 x 15 = 45

Therefore.,

Measures of 3 angles are

75°, 60° and 45°
