Please help me with the question below and i will mark you as BRAINLIEST

AB = 18   BC=8   CD=5

Let's call E that point at the other end of x, so x=DE.

Secant Secant theorem says

CE × CD = AC × BC

and since CE = CD + DE,   AC = AB + BC

(CD + DE) CD = (AB + BC) BC

Substituting,

(5  + x)(5) = (18 + 8) (8)

5  + x =  (26)(8)/5

x = -5 +  (26)(8)/5 = 183/5 = 36.6

36.6, last choice

17.25

Step-by-step explanation:

TOTAL ADDITION = 138 AND THERE ARE 8 NUMBERS

SO 138 DIVIDED BY 8 = 17.25
