Question

Find the length of the unknown side. Round your answer to the nearest tenth. 20 m 12 m b

Answer 1

The length of the unknown side is 16 meters

What is a right triangle?

A right triangle is a triangle that has one of its angles to be 90 degrees

The length of the unknown side is calculated using the following Pythagoras theorem.

$20^2 = 12^2 +b^2$

Evaluate the exponents

$400 = 144 +b^2$

Collect like terms

$b^2 = 400 -144$

Evaluate the like terms

$b^2 = 256$

Take the square root of both sides

$b = 16$

Hence, the length of the unknown side is 16 meters
