Question

A park in the shape of a right triangle, one leg of the triangle is 2 kilometers long, the hypotenuse measures 2.9 kilometers how long in kilometers is the other leg?

Answer 1

2.1 kilometers

Explanation:

Pythagoras' Theorem

a^2 + b^2 = c^2

2^2 + b^2 = 2.9^2

2.9^2 - 2^2 = b^2

8.41 - 4 = 4.41

b = √4.41

b= 2.1
