If m(RST) = 12x-1, m(RSU) = 9x-15, m(UST) = 53, find measures (all in degrees)

I am trying to help my daughter with this and not sure how to start. any help here would be greatly appreciated thank you.

Do you "see" that a diagram is required; are we to guess?

this is what else came with it. sorry about that

The angles all have vertex S; since the other points are in the order R,U,T, angle RST is the sum of RSU and UST, so you can write the equation

12x - 1 = (9x - 15) + (53)

Solve the equation, then plug that into each expression to find the measures of the angles.

If the picture had been different, the equation would be different.
