Cot=cos/sin
so, it becomes sin^2+cos^2=1
that proves it
√49=7

√16=4
√36=6
√144=12
√64=8
√81=9
√121=11

Mark brainliest please
Hope this helps you
Ok s we know the total cost is $320 so if the cost for the supplies is $70 the n we will subtract 70 from 320 leaving us with $250. The jobs is 5 hours so we will divide 250 by 5 and get 50 so the total cost per hour is $50
hope this helps!
