B.
Using this will give you proper representations in similar triangles.
Answer: 9.97
==============================================
Explanation:
y = distance from the base of the pole to the closest person
y+200 = total horizontal distance
-------------
Focus on the smaller right triangle.
tan(angle) = opposite/adjacent
tan(26) = 55/y
y*tan(26) = 55
y = 55/tan(26)
y = 112.76671 approximately
Make sure your calculator is in degree mode.
--------------
Now move to the larger right triangle
tan(angle) = opposite/adjacent
tan(x) = 55/(y+200)
tan(x) = 55/(112.76671+200)
tan(x) = 55/312.76671
tan(x) = 0.17585
x = arctan(0.17585) same as 
x = 9.97349
x = 9.97 degrees approximately

Answer:
d. $43.00
Step-by-step explanation:
Karli's total cost is ...
total cost = material cost + labor cost
= ($8.00/10 gal)·(5 gal) + ($13.00/h)·(3 h)
= $4.00 + $39.00
= $43.00
