Answer:
20 degrees
Step-by-step explanation:
we can consider 33 to be the radius of a circle.
31 would then be the cos of the angle in that circle.
the regular cos function is defined for the standard circle with radius 1. so, that would be multiplied by 33 for this circle here.
31 = cos(?) × 33
cos(?) = 31/33 = 0.9393...
? = 20.05 ≈ 20 degrees
18.63 is your answer please give brainliest!
Let
S=cost of software
4S=cost of computer
Total cost = $1200
=>
S+4S=1200
solve for S
5S=1200
S=240 (= cost of software)
Cost of computer = 4*240 = $960
