Question

find the measure of the angle marked with a? Using inverse trig functions. Round your answer to the nearest degree. part 3​

Answer 1

`\theta \approx 27.5\º`

Explanation:

Once

`$\sin(\theta) = \frac{\text{Opposite}}{\text{hypotenuse}} =(12)/(26)=(6)/(13) $`

And

`\arcsin \left((6)/(13) \right)=\theta`

`\theta \approx 27.5\º`

Answer 2

The unknown angle =

27°

Note :

SOH = Sin angle = Opposite/hypotenuse

CAH = Cos angle = Adjacent/Hypotenuse

TOA = Tan angle = Opposite/Adjacent
