Question

express the following degrees and minutes as decimal degrees. round the answers to 2 decimal places where necessary. 78°45 78.75 45.78 78.45 78.01

Explanation:

Step1: Convert minutes to degrees

Since \(1^{\circ} = 60'\), then \(45'=\frac{45}{60}\) degrees.
$$\frac{45}{60}= 0.75$$

Step2: Add to the degree part

We have \(78^{\circ}+0.75^{\circ}\).
$$78 + 0.75=78.75$$

Answer:

78.75
