<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 
Y=4x i believe is the answer
1. 5a
The multiplication sign isn’t always used in algebra, you can put the two things being multiplied together
For example 8x or 2xy
The last term is 58. List out the ways to multiply two whole numbers to get to 58
1*58 = 58
2*29 = 58
(-1)*(-58) = 58
(-2)*(-29) =58
Then go through those factors and see which two values add to 6 (which is the middle number in the given expression)
1+58 = 59
2+29 = 31
-1+(-58) = -59
-2+(-29) = -31
None of those sums are 6, so the original expression cannot be factored. It is said to be prime.
