Write the standard equation for the circle center (-6, 7), r= 9. O(x – 6)2 + (y + 7)2 = 9

(x – 7)2 + (y + 6)2 = 81

(x + 5)2 + (y – 7)2 = 81

(x+6)2 + (y – 7)2 = 9

(×+6)^2 + (y -7 ) ^2=81

Step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
