In the circle shown, AB is tangent to circle o at point and OC is a radius Which relationship is true?

A.

Step-by-step explanation:

According to tangent theorem, a tangent is formed when the radius of a circle is perpendicular to the line, meeting at a point around the circle, such that the tangent line would be perpendicular to the radius of the circle with a center.

Given that is a tangent of the circle O, at a point C, and is a radius, therefore, it follows that:

.

This means the radius of the circle is perpendicular to the tangent formed at point C.

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
