The hypotenuse of a right triangle is 10 cm long. One of the triangle’s legs is three times the other leg. Find the lengths of the three sides of the triangle. In case of non-integer answer?

Answer 1

The other 2 legs then are x and 3x

Pythagorean theorm tells us (x)^2 + (3x)^2 = (10)^2

x^2 + 9x^2 = 100

10x^2 = 100

x^2 =10

x= sqroot10= 3.16
