Question

the ratio of the angles of the tringle is 5:7:12 . prove that the tringle is a right tringle.

Answer 1

Answer:

Step-by-step explanation:

Since the angles are in the ratio 5:7:12, let the angles be 5m, 7m, and 12m

Then 5m+7m+12m=180

24m=180

m=7.5

So the angles are 37.5, 52.5 and90 degrees and hence it is a right triangle

Answer 2

let the ratio be X

according to question

5x +7x+12x = 180( angle sum property of triangle)

24x = 180

X = 180/24

X = 7.5

so angles will be respectively

5x= 5× 7.5= 37.5

7x= 7× 7.5= 52.5

12x= 12× 7.5= 90

so the given triangle is a right angle triangle...
