Question

2) The length of a step is 12 inches. In order to comply with safety regulations, the angle of elevation must be 60 degrees. What are the rise and run of the step?

Answer 1

12√3 / 12

Explanation:

this creates a 30,60,90 triangle and since we are trying to find the rising part of the run we are going to have to find the 60-degree angle part. So then we do 12 times root 3.
