Draw out the triangle ABC for better visualisation of where the points are

From there you can find angle BAC, and it is actually 90 degrees, therefore ABC is a right angled triangle.

You can then find angle ABC, which can be found by 360 - 250 - (180-135)

With this angle, you also have the length of BC, 50m. You can use trigonometry to find length AB and AC.

Using the length AB and angle of elevation, you can find the height of the tower. With that, use length AC to get the angle of elevation of T from C.

Go try it out. Hope it helps!
