Question

The sides of a triangle are in the ratio 5:3:7. If the perimeter of the range is 90 om
find the measures of its sides
​

Answer 1

Answer:

The angles of the triangle are in the ratio: 5:3:7

Let the angles be 5x,3x,7x

By Angle sum property,

5x+3x+7x=180

15x=180

x=12

Thus, angles are, 60

∘

,36

∘

,84

∘

Since, all the angles are less than 90

∘

, it is an acute angled triangle.

Answer 2

Answer:

X=7 sides 35 21 49

Step-by-step explanation:

let sides be X

thus ratio 5x 3x 7x

5x+3x+7x=90

15x=90

X=7
