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

Right triangle...you can use the Pythagorean Theorem

a² + b² = c²

'c' is your hypotenuse ....'a' and 'b' are the OTHER 2 legs....we have the hypotenuse...and one of the other legs....we need to solve for 'b'

\[b^2 = c^2 - a^2\]
\[b = \sqrt{c^2 - a^2}\]

input your values of 'a' and 'c' and find 'b'
