What are m<1 and m<2? A. <1= 30, m<2=35
B. <1=35, m<2= 30
C. <1=65, m<2=60
D. <1=85, m<2=80

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

remember about y=mx+b so she’s forgot to put the 3x to a fraction
