Chapter 5.5, Problem 1CFU

(a)

To determine

To tell: Whether the solution to $\tan {34}^{\circ }15\text{'}=\frac{x}{12}$ is an angle measure or a linear measurement.

Answer to Problem 1CFU

Linear measurement

Explanation of Solution

Given information: $\tan {34}^{\circ }15\text{'}=\frac{x}{12}$

Calculation:

This x is a linear measure,

Since it is one of the sides that make up the ratio

Thus, a linear measurement

(b)

To determine

To tell: Whether the solution to $\tan x=3.284$ is an angle measure or a linear measurement.

Answer to Problem 1CFU

Angle measurement

Explanation of Solution

Given information: $\tan {34}^{\circ }15\text{'}=\frac{x}{12}$

Calculation:

This x is an angle measure,

Since it is what the tangent is being taken of.

Thus, an angle measurement
