Question

Find each angle of a triangle which are in the ratio 5 : 3 : 1

Please tell​

Answer 1

Answer: 5:3:1

             Let us take a variable x

            SO, IT'S 5X,3X AND X

            WE KNOW THAT THE SUM OF ALL THE ANGLES OF A TRIANGLE

             IS 180 DEGREES

             5X+3X+X=180 DEGREES

                        9X=180

                          X=180/9

                          X=20 DEGREES

                          5X=5*20

                          5X=100 DEGREES

                          3X=3*20

                          3X=60 DEGREES

                            X=20 DEGREES.

Answer 2

Let us assume all the angles of triangle be 5x, 3x, 1x, respectively.

We know that,

Sum of all angles of triangle = 180°

=> 5x + 3x + 1x = 180°

=> 9x = 180°

=> x = 180° / 9 = 20°

Now,

First angle = 5x = 5*20° = 100°

Second angle = 3x = 3*20° = 60°

Third angle = 1x = 1*20° = 20°

Hope this helps, Please mark me as the brainliest.
