A man is in a boat that is floating 175 feet from the base of a 200 foot cliff. What is the angle of depression between the clif
LUCKY_DIMON [66]

Answer:

The of depression between the cliff and the boat is 48.74 degrees.

Step-by-step explanation:

We have,

Height of the cliff is 200 foot

Distance of boat from the cliff is 175 feet

It is required to find the angle of depression between the cliff and the boat.

Here, 200 foot is perpendicular distance and 175 is base.

Using trigonometry :

\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{200}{175}\\\\\theta=\tan^{-1}(1.14)\\\\\theta=48.74^{\circ}

So, the of depression between the cliff and the boat is 48.74 degrees.

Which of the following sets would have a graph with an open circle on 2 and a ray pointing left on the number line?
MaRussiya [10]
Hi, the graph you describe represents all real numbers smaller than 2, without the two (that's why there's the open circle). Hence the correct answer is the third choice <span>{x | x ∈ R, x < 2}.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

20 POINTS FOR YOUR TIME! PLEASE HELP!!
zheka24 [161]
For a relation to be function, every x value should have its unique image in    co-domain. If x is related to more than one y value, then that relation is not a function 
In 1, as you can see, 1 related to -7 as well as 8. Which means 1 has two images viz. -7 and 8. But for a relation to be function, x should have only one image. Thus, it is not a function.
The worst is the 4th one in which -2 has 4 images. 
Therefore, only relation B is a function.
