Question

Find the missing value to the nearest hundreth.

Sin______=9/16
Not sure how to find this DX

Any explanations would be greatly appreciated!!

Answer 1

Let A be the unknown.

sin A = 9/16 when we convert 9/16 to decimal

sin A = 0.5625

\[A = \frac{ 0.5625 }{ \sin }\]

which is equal to

\[A = \sin^{-1} (0.5625)\]

Using your calculator,

A = 34.23
