Question

Find the angle Ø to the nearest minute: sin Ø = 0.1655

1. 9° 32'

2. 9° 38'

3. 9° 39'

4. 9° 31'

Answer 1

Using your calculator and taking the inverse sin, you get Ø = 9.52628° so the answer is 9° and so many minutes.

To determine the number of minutes, we use the conversion that 1 degree is 60 minutes and using that conversion we convert to minutes:

= (0.52628)(60) minutes = 31.5769 minutes = 32 minutes

So 9° 32'
