Question

5. Find the missing reference angle using arcsin, arccos, or arc tangent. (Round to

the nearest whole number)
14
48
50
Your answer

Answer 1

16°

Explanation:

Reference angle =
`\theta`

Side Opposite to reference angle = 14

Adjacent side = 48

Hypotenuse = 50

Let's apply arcsin:

Thus:

`\theta = sin^(-1)((Opp)/(Hyp))` (recall: SOHCAHTOA)

Plug in the values

`\theta = sin^(-1)((14)/(50))`

`\theta` = 16.2602047° = 16°
