Can anyone me solve these math problems? if you don’t mind, tell me how you got the positive angle and negative angle.

Question-1:

Formula of a circle is (x-h)^2+(y-k)^2=r^2 where (h,k) is centre and r is radius

Question-2:

The formula for finding a coterminal angle is(θ+360k) where θ is the given angle and k is an integer(positive or negative) ..the least negetive coterminal (where k=1 )of -35 is=(-35-360×1)=-395 and the least positive coterminal(k=1)of -35 is=(-35+360×1)=325

h who knows

step-by-step explanation:

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
