Chapter 2.2, Problem 4PSA

To determine

To calculate: Complement of ${61}^{\circ }21\text{'}13"$

Answer to Problem 4PSA

  ${28}^{\circ }38\text{'}47"$

Explanation of Solution

Formula Used: complement of an angle $x^{\circ }$ is ${(90-x)}^{\circ }$ .

Calculation: complement of is $({90}^{\circ }-{61}^{\circ }21\text{'}13")$ write ${90}^{\circ }$ as ${89}^{\circ }60\text{'}60"$

Now, ${89}^{\circ }60\text{'}60"-{61}^{\circ }21\text{'}13"$

  $={28}^{\circ }38\text{'}47"$
