Lilly is making a bike ramp on the sidewalk in front of her house. She places a wood plank on top of blocks to form the ramp. The blocks are one foot in height, and the distance from the base of the blocks to where the wood plank touches the sidewalk is five feet. What is the approximate angle formed between the sidewalk and the base of the ramp? (1 point)
The angle formed between the sidewalk and the base of the ramp can be calculated using the tangent function.
Tangent(angle) = opposite / adjacent
In this case, the opposite side is the height of the blocks which is 1 foot, and the adjacent side is the distance from the base of the blocks to where the wood plank touches the sidewalk, which is 5 feet.
Tangent(angle) = 1 / 5
Using a calculator, the approximate angle formed is 11.31 degrees.
