Answer:
A = 15 cm^2
Step-by-step explanation:
The area of a triangle is found by
A = 1/2 bh

Well the answer i think is going to be 18
Answer:
The length of the rope between the boat and the dock is of 30 feet.
Step-by-step explanation:
Given:
tan(40) ≈ 0.839
Angle of depression = 40 (deg)
Distance between boat and the floor of the ocean = 25.17 feet
If we look into the diagram we can see that,they form 2 right angled triangle.
Where we can say that :
Distance between boat and dock = Rope's distance = Base of the triangle.
Let the length of the rope be 'x' feet.
Considering the dotted triangle:

⇒
⇒ 
⇒ 
⇒ 
⇒
⇒ 
Length of the rope between the boat and the dock is 'x' = 30 feet.
Answer: x=3.537715
Step-by-step explanation:
5x+3=300
5x+3+−3= 300+ −3
5x=297
Step 2: Solve Exponent.
5x=297
x=3.537715
Hope this helps :)
Well CD and CB are both equal to each other because they’re the same angles , it’s a reflection
