Question

Solve for x. Help me out because I haven’t been paying attention all year

Answer 1

x = 18

Explanation:

(whole secant) x (external part) = (whole secant) x (external part)

(6+x)6 = (8+10)* 8

6*(6+x) = 8(18)

Divide each side by 6

6+x = 8(18)/6

6+x = 8*3

6+x = 24

Subtract 6 from each side

6+x-6 =24-6

x = 18
