I think it is, (1,1) I think that is it...
We can use tangent to calculate the length of ST.

Here, the opposite side of the 60 degree angle is ST, and the adjacent is RS. Plug in what we know, we can use 'x' for side ST:

Solve for 'x', multiply 7 to both sides of the equation:

This is an exact answer for the length of ST, we can find an approximate with a calculator:
Answer:
the answer is (56/100)×100%= 56%
Make them into fractions. 9/3, 480/32, and 10/4. Now try to make the denominators the numbers below the shape and then find the number that works for that fraction.
