Text Solution

Verified by Experts

The correct Answer is:
D
Since you are given the opposite and adjacent sides, try using tangent.
`tan theta = ("opposite")/("adjacent")=(5)/(4)=1.25`
Now use the `tan^(-1)` function on your calculator (probably ''2nd'' and then ''tan'') to find
`tan^(-1)(1.25)=51.34019175`
