Ireally appreciate it and need it. i'll give all i have for both questions maybe brainliest

Problem 5

Each two tangents form a right angle from the center of the circle to the circumference (a radius) and from the circumference to the exterior point. That makes a kite of 2 tangents and 2 radii.

The radii make an angle of 360 - 2*90 - 47 = 133.

That is also the central angle for the arc you are asking about.

133.

Problem 9

The center is at point (-6, - 8) So far what you have is

(x + 6)^2 + (y + 8)^2 = r^2

You use the two given points to find r^2

r^2 = (x2 - x1)^2 + (y2 - y1)^2

r^2 = (-6 - 0)^2 + (- 8 - 0)^2

r^2 = 36 + 64

r^2 = 100

The circles equation is (x + 6)^2 + (y + 8)^2 = 100
