Brainliest <br> Please do one of the above<br> (I would appreciate if you did more then one)
Temka [501]

Answer:

a) 52.5 ft. b)40.1ft c)12.5ft d) 72.6

Step-by-step explanation:

a) The height of the lighthouse is 84ft, and the angle of elevation is 58 degrees.

tan58=84/x

find x by dividing 84 by tan58, and you get 52.5ft.

b) do the same thing, except 131 is in the base of the right triangle shape. That being said, do tan17=x/131.

multiply 131 by tan17, and you get x=40.1 feet.

c) This question wants you to find the length of the slide, (basically the hypotenuse).

given the angle to be 46, do sin46=9/x

since sin is opp/hyp

9/sin46= 12.5ft

d) Find the angle of elevation by using inverse tan given the base to be 5, and the height to be 16ft.

tan^-1=(16/5)=theta

x=72.6 hope this helps!

Use the pythagorean theorem to find the missing side. Round your answer to the nearest tenth
Monica [59]

Answer:

x=14.02

Step-by-step explanation:

Use b=\sqrt{c^2-a^2} to solve for the missing side in the triangle. You will get a rounded answer of 8.49. Then you multiply that by 2 and subtract that value from 31. Then that will be your answer.

How to know when to use which probability distribution?
worty [1.4K]
57% of students studied, which decomposes into  52% who both studied and saw an increase in their exam grade  5% who both studied and did Not see an increase in their exam grade The percentages above are relative to the whole population of 100 students, to get the requested probability, recall that:   One way to find out the probability of an event is to  Take the ratio of the number of times the event happened, over the total number of times the event could have happened.    Total number of times the event happened:    52 = 52% of 100 students studied and saw an increase in their exam grade  Total number of times the event could have happened:    57 = 57% of 100 students studied
