Question

Find the length of the missing side for a right triangle with the given sides. Side c is the hypotenuse. Sides a and b are the legs. Hint: Draw a picture. Include the units as part of your answer. a = 21 m c = 29 m

What is the length of B?
How many units are there?

Answer 1

You can calucate b by using pythagorean theorem:

a² + b² = c²

21² + b² = 29²

b² = 841 - 441 = 400

b = √400 = 20 (m)
