Answer:
The correct answer is 7.54 foot apart.
Step-by-step explanation:
The height of the Cap San Juan Lighthouse is 45 foot.
The angle of depression of the first boat is given to be 40°.
Distance between the first boat and the lighthouse is cos 40° × 45 = 34.47 foot.
The angle of depression of second boat is given to be 21°.
Distance between the second boat and the lighthouse is cos 21° × 45 = 42.01 foot.
Therefore the boats are 42.01 - 34.47 = 7.54 foot apart from each other.
Answer:
(-5,-3)
Step-by-step explanation:
In this case to find the solution you could use substitution. This way you can solve without changing the equation over again.
(b - 2) - 3b = 4
b - 2 - 3b = 4
-2b - 2 = 4
-2b = 6
b = -3
Plug back in to find value a
a = (-3) - 2
a = -5
Check your answer before submitting
(-5) - 3(-3) = 4
-5 + 9 = 4
4 = 4
