Answer:
125$
Step-by-step explanation:
if it's proportional that means it will move up or down in equal amounts
going down from 20 to 5 kg means I divided by 4
so I can also divide 500 by 4 and get 125$
From my understanding you ahould use the trig function cos to solve this.
cos(c) = 15/25 or 0.6
if you have this following function on your calculator I suggest using it:
cos ^{ - 1}
by using the function like so:
cos^{ - 1} (0.6
you should get about 53.13° (rounding to the nearest hundredth)
Hope this helped.
