Question

Identify the correct trigonometry formula to use to solve for the given angle.

Answer 1

D

Explanation:

So we want to figure out the measure of angle ?.

We already know that sides opposite and adjacent to the angle.

Therefore, we need to use tangent. Recall that tangent:

`\tan(?)=opp/adj`

Substitute 34 for the opposite and 48 for the adjacent:

`\tan(?)=34/48`

Divide (approximately):

`\tan(?)=0.71`

Take the inverse tangent of both sides:

`?=\tan^(-1)(0.71)`

So, our answer is D

And we're done!
