Question

John is standing in front of a tree at point S. He can see an arc of the tree trunk that stretches from J to K measuring 64°:

The figure shows a circle with points J and K on it and point S outside it. Tangents to the circle at point J and K are drawn from point S. Minor arc JK measures 64 degrees

What is the measure of angle JSK?

58°

116°

148°

32°

Answer 1

minor arc = 64
major arc = 360-64 = 296

=> angle = (296 - 64)/2 = 116 degrees

Answer 2

@aballer101 THANKS SO MUCH!!!!!!!!!!!

Answer 3

need help with anything else?

Answer 4

YES

Answer 5

Which of the following is a step in constructing a circle circumscribed about a triangle?

Use a compass to locate the intersection of the midpoint of each side.

Use the perpendicular bisectors to find the center of the circle.

Use a compass to locate the intersection of the altitude of each side.

Use the angle bisectors to find the center of the circle.

Answer 6

maybe B?

Answer 7

yes it is B

Answer 8

Perpendicular bisectors help you find the center of a circle circumscribed about a triangle.

Answer 9

The center of the circumscribed circle is called the circumcenter.
The circumcenter must be equidistant from all three vertices.
Therefore, the circumcenter must lie on the intersection of .... ?
