A manager is comparing the cost of buying baseball caps from two different companies.
.
Company X charges a $60 fee plus $5 per baseball cap.
Company Y charges a $15 fee plus $8 per baseball cap.
.
For what number of baseball caps will the cost be the same at
both companies

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

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
