Answer:

1) No

2) Yes

3) angle UXS = 120 degrees

4) arc CB = 40 degrees

Step-by-step explanation:

If AB is tangent to the circle, then angle at A would be 90 degrees.

1)

Is 13^2 + 14.6^2 = 19.4^2?

169 + 213.16 = 376.36      No

2)

Is 8^2 + 6^2 = 10^2?

64 + 36 = 100      Yes

3)

arc WS = arc VU + arc TU = 113 degrees

arc ST = arc WV because their chords cross making a pair of vertical angles.

full circle = 360 degrees

360-113 - 113 = 134 degrees

134/2 = 67 degrees for arc ST

arc STU = 67 + 53 = 120 degrees

Angle UXS = 120 degrees

4) arc CB = arc FB =  40 degrees because their chords cross making a pair of vertical angles.
