6x + 6(3) = 108
6x + 18 = 108
6x = 108 - 18
6x = 90
x = 90/6
x = 15 <== the access fee per visit

ΔABC ≅ ΔDEF
I find it easier to see the congruencies if I write them underneath each other:
∠A ≅ ∠D ≅
∠B ≅ ∠E ≅
∠C ≅ ∠F ≅
A^2 + b^ = c^2
a^2+ 1^2 = 5^2
a^2+ 1 =25
-1. -1
a^2 = 24
square both sides and you get a= the square root of 24
Answer:
cosA = 40/41
tanA = 9/40
Step-by-step explanation:
Step 1: Find the other leg value
a² + b² = c²
9² + b² = 41²
b² = 41² - 9²
b = √1600
b = 40
Step 2: Draw out your triangle.
When you do so, you should see the cosA (adjacent over hypotenuse) is 40/41 and tanA (opposite over adjacent) is 9/40.
Triangle CBA
Length of AC = 40 (Leg)
Length of BC = 9 (Leg)
Length of AD = 41 (Hypotenuse)
cosA = AC/AB = 40/41
tanA = CB/AC = 9/40
