Answer:
x = 200/3
Step-by-step explanation:
Apply Thales theorem, we have:
80/(2x) = 60/27
Let's simplify both sides:
40/x = 20/9
or
x/40 = 9/20
Multiplying both sides by 40, we have:
(40/40)x = (20/9)*40
Let's simplify one more time:
x = (20*40)/(9)
or
x = 200/3
Hope this helps!

Answer:
B. 9.9 ft
Step-by-step explanation:
You have a right triangle, so you can use the Pythagorean theorem.
a^2 + b^2 = c^2
15^ + x^2 = 18^2
225 + x^2 = 324
x^2 = 99
x = sqrt(99)
x = 9.9
