Question

Pythagorean Theorem Task Card #2 Seth drives due north for 18 miles then east for 9 miles. How far is Seth from his starting point? Round to the nearest tenth if necessary.

Answer 1

A right triangle is made where the two legs are 18 miles (a) and 9 miles (b). We have to find the hypotenuse (c). Using Pythagorean Theorem:

c² = a² + b²

c² = 18² + 9²

c = √405

c = 20.1 miles
