we are given a polygon with 6 sides, therefore, is a hexagon. The interior angles of a hexagon always add up to 720 degrees.

Using the expression and the given angles, we can construct the following relationship:


(x+80)+135+(x+50)+130+(x+75)+115=720

Solving the operations we get:


3x+585=720

Now we solve for "x" first by subtracting 595 to both sides:


\begin{gathered} 3x=720-585 \\ 3x=135 \end{gathered}

Now we divide by 3:


x=(135)/(3)=45

Therefore, x = 45.

Now we use the expression for angle T:


\angle T=x+50

Replacing the value of x, we get:


\angle T=45+50=95

Therefore, angle T is 95 degrees.
