In the diagram below of circle O, secant AB intersects circle O at D, secant AOC intersects circle O at E, AE = 8, OE = 14, and AB = 24. What is the length of AD?

part a: 1.08

part b: 27.59

h= 12 inches

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
