Here is a hanger: 1. Write an equation to represent the hanger.

2. Draw more hangers to show each step you would take to find

3. Write an equation to describe each hanger you drew. Describe
how each equation matches its hanger.

the answer will be the last one

hi how are you doing today? if you ever need just tell me

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
