Question

7 multiple choice 1 point these exercises require the addition of angles. determine the value of each. 21°50 + 7°17 28°67 28°10 29°7 29°67

Explanation:

Step1: Add degrees and minutes separately

$$\begin{align*} \text{Degrees: }21^{\circ}+ 7^{\circ}&=28^{\circ}\\ \text{Minutes: }50'+17'&=67' \end{align*}$$

Step2: Convert minutes to degrees if necessary

Since \(60' = 1^{\circ}\), then \(67'=1^{\circ}7'\)

Step3: Add the converted degree to the previous degree sum

\(28^{\circ}+1^{\circ}7' = 29^{\circ}7'\)

Answer:

\(29^{\circ}7'\) (corresponds to the third option \(29^{\circ}7'\))
