I cant figure out the answer for this can you help me

RV = 5, AV = 9

Step-by-step explanation:

Two secants to a circle from an external point, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is

4(4 + RV ) = 3(3 + 9), that is

16 + 4RV = 3 × 12 = 36 ( subtract 16 from both sides )

4RV = 20 ( divide both sides by 4 )

RV = 5

and AV = 4 + 5 = 9

maybe - definition of supplementary angles. im not sure. sorry
