Question

The side view The side view of a ramp that jessie built for his race cars is shown below. Find r, the length of the ramp to the nearest tenth. please show step by step instructions using Pythagorean Theorem.

Answer 1

Answer: B. 15.7 inches

Explanation:

The ramp forms a right angle triangle. The height of the ramp above the ground represents the opposite side of the triangle. The length of the ramp represents the hypotenuse of the right angle triangle. The base of the ramp represents the the adjacent side of the right angle triangle. Therefore, to find r, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

r² = 7² + 14² = 49 + 196

r² = 245

r = √245

r = 15.7 inches to the nearest tenth
