Answer:

You may have gotten the opposite and adjacent mixed up.


(24)/(7)

Explanation:

An easy way to remember these trigonometric ratios is by using SOHCAHTOA, where:

SOH stands for-


Sine=(Opposite)/(Hypotenuse)

CAH stands for-


Cosine=(Adjacent)/(Hypotenuse)

TOA stands for-


Tangent=(Opposite)/(Adjacent)

We are asked to find tan 74° given the right triangle. To find this, we must find the lengths of the opposite side and the adjacent side of the 74° angle. From looking at the triangle, we can see that the side opposite from the 74° angle is 24, and the adjacent is 7. So plugging it into the trigonometric ratio that we found using SOHCAHTOA, we find that:


tan74=(24)/(7)

So the answer would be
(24)/(7)

Seeing as how you picked
(7)/(24) as your answer, it seems that you may have gotten the opposite and the adjacent mixed up or used
tangent=(adjacent)/(opposite) as your trigonometric ratio.

I hope you find my answer and explanation to be helpful. Happy studying.
