Angle abc is formed by two tangents intersecting outside of a circle. if minor arc ac = 110°, what is the measure of angle abc?

Step-by-step explanation:

Given that two tangents to a circle intersect at a point B outside the circle

A and C are points of contact.

By theorem on circles we have angle ABC is equal to 1/2 the difference of intercepted arcs.

Angle of minor arc =110 and hence major arc

Difference =

Measure of angle ABC 1/2 of 140 = 70 degrees.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
