Answer:

3 floors.

Step-by-step explanation:

We have been given that an elevator goes up 7 floors.

We know that going up is a positive altitude, so 7 floors up will be positive 7.

Then the elevator comes down 4 floors. We know that coming down is a negative altitude, so coming down 4 floors would be -4 floors.

The change in the floor would be +7-4=3 floors.

Therefore, the change in the floor level is 3 floors.

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!
