A line is tangent to the circle only if it is perpendicular to the radius drawn to the point of tangency

No, point D is not tangent to the circle.

Yes

682 + 512 = 852

No

82 + 162 192

Solve for x.

x2 + 962 = 1002

x = 28

Solve for x.

x2 + 482 = 802

x = 64

Solve for x.

x2 + 322 = (x + 16)2

32x = 768

x = 24

Solve for x.

x2 + 562 = (x + 32)2

64x = 2112

x = 33

Solve for x.

x2 + 992 = (x + 81)2

162x = 3240

x = 20
