Pythagorean Theorem Word Problems Challenge

The video tutorial explains how to solve two word problems using the Pythagorean theorem. The first problem involves calculating the straight-line distance from a starting point after driving north and east, forming a right triangle. The second problem involves determining the height of a TV given its diagonal and width, again using the Pythagorean theorem to find the missing side of a right triangle.

What is the straight-line distance from the starting point after driving north for 21 miles and then east for 20 miles?

• 20 miles

• 41 miles

• 29 miles

• 21 miles

Which side of the triangle is represented by the diagonal length of the TV?

• The hypotenuse

• The height

• The base

• The area

What formula is applied to find the height of the TV?

• a^2 + b^2 = c^2
