Mrs. Hussen has two similar recycling bins in her office. The dimensions of the smaller bin can be found by dilating the dimensions of the larger bin by a scale factor of 0.75.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

can i see the following ?

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
