Answer:

44.1

Step-by-step explanation:

Cosine = Adjacent over Hypotenuse

Adjacent of ∠T = 28 and hypotenuse = 39

Which means that  cos(x)=\frac{28}{39}

Now we solve for x

To get rid of the "cos" we take the inverse of cos ( which is cos^-^1 ) and apply it to each side

cos^-^1((cos)x) = x\\cos^-^1(\frac{28}{39} )=44.11461855

We're left with x = 44.11461855

Our last step is to round to the nearest tenth and we get that the answer is 44.1
