Question

Find the cosine of ∠T.
36
77
T
S
U
Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
cos(T)=

Answer 1

I don't have the full diagram — can you confirm which side is which?

Possible interpretations and results:
- If the triangle is right and the side of length 77 is the hypotenuse while the side of length 36 is the adjacent side to ∠T, then cos(T) = 36/77.
- If instead 36 and 77 are the two legs of a right triangle with ∠T between them, then the hypotenuse is sqrt(36^2+77^2) and cos(T) would be (adjacent leg)/hypotenuse — tell me which leg is adjacent.
- If it's a non-right triangle, I need the third side or more information to use the Law of Cosines.

Please upload the diagram or say which side is the hypotenuse/which side is adjacent to ∠T and I'll finish it.
