What is the value of Sine theta in the diagram below?

A unit circle is shown. A radius with length of 1 forms angle theta in the first quadrant. The radius goes to point (StartFraction 7 Over 25 EndFraction, StartFraction 24 Over 25 EndFraction) on the unit circle.
StartFraction 7 Over 25 EndFraction
StartFraction 7 Over 24 EndFraction
StartFraction 24 Over 25 EndFraction
StartFraction 24 Over 7 EndFraction
