Question

Find the length of the unknown side. Round your answer to the nearest tenth.

Answer 1

Answer: 8 meters (choice D)

Reason:

Use the pythagorean theorem to find the missing side.

`a^2 + b^2 = c^2\\\\a^2 + 15^2 = 17^2\\\\a^2 + 225 = 289\\\\a^2 = 289-225\\\\a^2 = 64\\\\a = √(64)\\\\a = 8`
