10cm because 8 is nearest to 10
TSP makes a right triangle with TS and TP being the sides and SP being the hypotenuse.
Using the Pythagorean theorem and the two given sides you can solve for the hypotenuse.
SP = √6^2 + 8^2
SP = √36+64
SP = √100
SP = 10 cm.
You can just use sine.
Sin(F) = opposite/hypotenuse = 28/40.
F =
(28/40)
