Question

Find θ in degrees, minutes and second, given: sin θ = 0.9205

Answer 1

66°59'57.4379"

Explanation:

A suitable calculator can find the angle whose sine is 0.9205 and convert that angle to degrees, minutes, and seconds

θ = arcsin(0.9205) ≈ 66.999288° ≈ 66°59'57.4379"

___

Multiplying the fractional part of the degree measure by 60 minutes per degree gives the minutes measure:

0.999288° ≈ 59.95730'

And multiplying the fractional part of that by 60 seconds per minute gives the seconds measure:

0.95730' = 57.4379"

In total, we have 66°59'57.4379"
