Answer:

\text{Decimal degrees} = 61.65^\circ    

Step-by-step explanation:

We are given the measure of an angle in degrees, minutes and seconds.

We have to convert this measure in decimal degrees.

\text{Measure of angle =} 61^\circ38'45''

1 degree equals 60 minutes or 3600 seconds.

The conversion is done with the help of formula:

\text{Decimal degrees} = d + \displaystyle\frac{m}{60} + \frac{s}{3600}\\\\\text{where d is the degree measur, m is the minute measure and s is the second measure.}

Putting the values, we have:

\text{Decimal degrees} = d + \displaystyle\frac{m}{60} + \frac{s}{3600}\\\\= 61 + \frac{38}{60} + \frac{45}{3600} = 61.65^\circ

A suitable calculator* can do this easily.

61°38'45" = (61 +(38 +45/60)/60)° ≈ 61.65°

I like the RealCalc app for Android, but many graphing calculators also will do this conversion. Of course, you can simply evaluate the expression as above.

Answer:

The answer is 60 degrees.

Step-by-step explanation:

The three angles in any triangle add up to 180 degrees.

You know by the box at the bottom right that it's a right triangle and therefore that angle is 90 degrees. They also give you the 30 degree angle at the bottom left. So:

90 degrees + 30 degrees = 120 degrees.

180 degrees (total) - 120 degrees (first 2 angles) = 60 degrees (missing angle)
