Which is a right triangle (15,30,35) (15,36,39) (15,20,29) (5,15,30)

Step-by-step explanation:

35^2 - 30^2 does not equal 15^2, so first one is not a right angled triangle,.

39^2 - 36^2 = 15^2 so It is a right angled triangle.

29^2 - 20^2 does not equal 15^2, so it isn't a right angled triangle.

30^2 - 15^2 does not equal 5^2, so it isn't a right angled triangle either.

Only right angled triangle in the set of 4 is (15,36,39)
