Find the values of x, y, and (a) Find the value of x
(b) Find the value of y
(C) Find the value of z

go and ask your mom to you

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

i dont know the answer but here's a picture of a dog

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
