Question

the measure of three angles of a triangle are in the ratio 5:3:1.find the measure of this angles

Answer 1

let the angles be x
sum of the angles of a triangle=180

5x+3x+x=180
9x=180
x=20
angle 1=5x
            =5*20=100
angle 2 =3x=3*20=60
angle 3=x=20

Answer 2

Hey user here is your answer.... .

________________________________

✅Let the angle be x

So angles are 5x, 3x, 1x

✔️5x+3x+x=180

⭕️Because we know sum of three angle in triangle is equals to 180°

⭕️By angle sum property of triangle

◆5x+3x+x=180

◆9x=180

◆x=180/9

◆x=20

✔️So the angles are 5x , 3x & x

✔️ Therefore 5(20)=100°, 3(2)=60° , x=20°

✅So the three angels of triangle are 100°, 60°, 20°
