A theorem in geometry states that the measure of an inscribed angle is half the measure of it's intercepted arc. In the figure, angle C intercepts arc AB and Line AB is the diameter of the circle. Which equation is a step in showing that m angle C = 90 degrees?

Adaylily farm sells a portion of their daylilies and allows a portion to grow and divide. the recursive formula an=1.5(an-1)-100 represents the number of daylilies, a, after n years. after the fifth year, the farmers estimate they have 2225 daylilies. how many daylilies were on the farm after the first year?
