(A)
Step-by-step explanation:
Given: sin ___ = 7/12
To find: The missing angle of sine.
Solution: Let the missing angle be A, then the given equation can be written as:
![sinA=\frac{7}{12}](/tpl/images/0346/3095/a90a0.png)
Taking sin inverse on both sides, get
![A=sin^{-1}\frac{7}{12}](/tpl/images/0346/3095/640ed.png)
![A=sin^{-1}(0.583)](/tpl/images/0346/3095/4a8c7.png)
![A=35.69^{\circ}](/tpl/images/0346/3095/fbef4.png)
Therefore, value of the missing angle is
, thus option A is correct.
