<u>Answer:</u> The ratio that represents the cosine of ∠T is
<u>Step-by-step explanation:</u>
We are given:
UV = 56 units
VT = 33 units
UT = 65 units
∠V = 90°
Cosine of an angle is equal to the ratio of base and the hypotenuse of the triangle. ΔTUV is drawn in the image below.
Base of the triangle is UV and the hypotenuse of the triangle is TU
Putting values in above equation, we get:
Hence, the ratio that represents the cosine of ∠T is
