The sum of x and y is greater than 0. When y is subtracted from x, the difference is less than or equal to 0. Which system of inequalities could you use to solve for x and y?
es )
A)
x+y> 0 and x - y so
B
B)
x+y<0 and x - y so
C)
x-y> 0 and x+y0
D)
x+y> 0 and x - y20

36 is the final answer! : )

$12. that is my answer.

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

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
