In the diagram below, ab and bc are tangent to o. which equation could be solved to find y, the measure of adc

A

Step-by-step explanation:

∠ABC is formed by 2 tangents to the circle and is measured as

∠ABC = (m  arc ADC - m arc AC ), that is

(y - 119) = 61 → A

A.

Step-by-step explanation:

We have been given a diagram. We are asked to choose the equation that can be used to solve for y.

We know that measure formed by two intersecting tangents outside a circle is half the difference of corresponding arcs.

Switch sides:

Therefore, option A is the correct choice.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
