I need help i don't know this

Below.

Step-by-step explanation:

Comparing the given equation with the standard form for a circle:

(x - h)^2 + (y - k)^2 = r^2

(x - 3)^2 + (y + 3)^2 = 36

- we see that the center (h, k) = (3, - 3) and the radius r = 6.

So place you compass point at  the center (3, -3) and set your compass span to 6 units and draw the circle.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

what is the answer?
