In circle 0 (drawn below), chords AB and CD intersect at point E. Also within this circle
are secant FDA and tangent FB that are drawn to circle O from external point F. Chord AC is
also drawn. Given that the mDA - 56, MDB - 112, and the ratio of MAC:MCB - 3:1,
answer the following questions (be sure to justify your responses):
a. Find mZCEB.
b. Find mZF.
c. Find mZDAC.

Lian is deciding which of two gyms to join. each gym charges a monthly rate plus a one-time membership fee. lian correctly wrote and solved a system of linear equations by substitution to compare the costs of the memberships. in her work, she substituted an expression for one variable and solved for the other. this resulted in the equation 75 = 75. what can lian conclude? one gym charges $75 per month. each gym charges $75 per month both gyms charge the same monthly rate and the same membership fee. both gyms charge the same monthly rate, but not the same membership fee.
