Question

Q5- The angles of a triangle are in the ratio 5:3: 7. Find the angles?​

Answer 1

Step-by-step explanation:

The angles of triangle = 5x,3x and 7x

We know Sum of all angles of triangle= 180°

5x + 3x + 7x = 180°

15x = 180°

x= 180/15

x= 12°

hence, 5x = 5× 12 = 60°

3x= 3×12 = 36°

7x = 7×12 = 84°

Answer 2

Answer:

HOPE IT HELPS MARK BRAINLIEST!!!!!

Step-by-step explanation:

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.
