Question

For the values a = 2.9 which is a leg of a right triangle, and value c = 4.2, which is the hypotenuse, find the length of the other leg, b, to the nearest tenth

Answer 1

Use Pythagorean Theorem,

(leg)^2 + (leg)^2 = (hypotenuse)^2.

Plug in 2.9 for one leg, and 4.2 for the hypotenuse in the above equation.

Then solve the equation for the remaining leg.
