Question

a wheel chair ramp will start 30 feet from a building and will slope 4 feet up. how long is the ramp to the nearest tenth.

Answer 1

30.3 feet

Explanation:

we are given two legs of a right triangle

so we can use pythagorean theorem for this problem

a^2 + b^2 = c^2

30^2 + 4^2 = c^2

900 + 16 = c^2

916 = c^2

c = 30.265

Answer 2

This problem can be treated as a right triangle. The Pythagorean theorem can be applied.

From the given, the height is 4 feet and the adjacent length between the building and foot of the ramp as 14 feet.

Applying the theorem, we have.

ramplength2 2height"+adjacent ramplength² = -42+142- 16196212 = ramplength 212 14.56021978≈ 14.6
