Final answer:
To find the measure of the indicated angle (?), use a protractor to measure the angle it makes with the reference frame. Convert the angle to decimal degrees if it is given in degrees, minutes, and seconds.
Step-by-step explanation:
The measure of the indicated angle (?) can be found using trigonometric relationships. To do this, we need to use a protractor to measure the angle it makes with the reference frame. If the angle is given in degrees, minutes, and seconds, we can convert it to decimal degrees by dividing the minutes by 60 and the seconds by 3600, and adding these results to the degrees.
For example, if the angle is 35 degrees, 43 minutes, and 9 seconds, the decimal degree measurement would be:
35 + (43/60) + (9/3600) = 35.719167 degrees.
