Question

A student and a flagpole cast a shadow at the same time of day

Answer 1

Answer: 49.3 ft

Explanation:

We will set up a proportion to help us solve this question.

`\displaystyle \frac{84\;\text{ft}}{x\;\text{ft}} =\frac{9.2\;\text{ft}}{5.4\;\text{ft}}`

Next, we will cross-multiply.

9.2 * x = 84 * 5.4

9.2x = 453.6

Lastly, we will divide both sides by 9.2 to solve and isolate the variable.

x = 49.3 ft
