We are asked to determine the sinT. To do that let's remember that the function sine is defined as:
In this case, we have:
To determine the value of VU we can use the Pythagorean theorem which in this case would be:
Now we solve for VU first by subtracting TU squared from both sides:
Now we take the square root to both sides:
Now we plug in the values:
Solving the squares:
Adding the values:
Now we separate the square root:
Solving the square root:
Now we plug in the values in the expression for sinT:
Now we simplify by canceling out the 6:
And thus we obtained the expression for sinT.
