Answer:
∠T≈44.1
Step-by-step explanation:
Please see the attached image.
Relative to ∠T, we know the adjacent side and the hypotenuse, 28 and 39 respectively.
We can use a trig function to solve for ∠T. When given the adjacent side and hypotenuse, we can use cosine.
The cosine of an angle is the adjacent side to that angle over the hypotenuse.
cos(T)=28/39
T=(28/39)
T≈44.1
