Am I the only one up rn nvm I gtg sleep lol but answer this anyway

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
