Question

A right triangle has one leg with a length of 30 and a hypotenuse with length of 35. What is the length of the other leg to the nearest whole number?

Answer 1

Use the pythagorean theorem.
a^2 + b^2 = c^2
a and b are the legs of the triangle while c is the hypotenuse.
So,
30^2 + b^2 = 35^2
b^2 = 1225-900
b = sqrt(325)
b =18.028
The length of the other leg is 18 ( to the nearest whole number )
