x = 60°

Step-by-step explanation:

AOB    Center: O      AB: diameter

arc ADB = 180°

arc DB = 180 - arc AD = 80°

x = 1/2 x ( arc DB + arc AC) = 1/2 x (80 + 40) = 60°

Solve for x.<br><br> A. 37<br> B. 27<br> C. 30<br> D. 31
dexar [7]

Answer:

B

Step-by-step explanation:

The formula for finding the relationship between a secant and a tangent is

tangent length ^2 = external segment secant/full length of secant

In this case

60^2 = 48*(x + 48)                   Expand

3600 = 48*(x + 48)                  Remove the brackets/

3600 = 48x + 48^2                 Expand

3600 = 48x + 2304                Subtract 2304 from both sides

3600 - 2304 = 48x              

1296 = 48x                              Divide both sides by 48

1296 / 48 = x        

x = 27
