Easy Trig help!

Answer 1

Well, post your problem, and see who shows up. People don't tend to commit until they see if the problem is something they can teach well, and that the questioner is committed to doing her part.

Answer 2

a) What is the vertical rise per step? (In inches rounded to the nearest whole inch)

b) Find the number of steps needed to climb from road level to the front entrance.

2) Indoor steps generally are steeper and have smaller landings. A staircase has a 9 inch vertical rise per step to get to the second floor of a house. If the angle of elevation is 48.3 degrees and there are 16 feet of horizontal space total for each of the landings combined, calculate the following questions (you must show all work to receive full credit):


a) What is the landing space per step? (In inches rounded to the nearest tenth)

b) Find the vertical rise from the 1st floor to the 2nd floor to the nearest foot.

3) A third staircase in a swimming pool has a landing of 18 inches and a vertical rise of 12 inches per step. To the nearest degree, calculate the following measures (you must show all work to receive full credit):


a) What is the angle of elevation rounded to the nearest whole degree?

b) If the elevation of each step were changed to 23 inches and the landing became 19 inches,
what is the new angle of elevation for the staircase to the nearest whole degree?

Answer 3

Those are all of them, but once i get the hang of it I shouldn't need help with them all.

Answer 4

draw a triangle. label the sides and angles that you know (that they told you about)
can you do that?

Answer 5

i'm not sure where to place what measurements

Answer 6

in the picture they show the "landing" and they show the angle. and you know one angle is 90 deg.

Answer 7

15 would be the one pointing straight up

Answer 8

how long is the landing?

Answer 9

well the vertical one is 31

Answer 10

but I'm not sure the length of the landing

Answer 11

the "angle of elevation" is 31 degrees. Angles are not sides.
in the picture, they show which angle is 31 degrees.
if you read the info carefully, they tell you how long the landing is. (and they label the side that is the "landing")

Answer 12

the landing of each step is 20 inches... so would i multiply 20 by how many steps there are?

Answer 13

usually we try to understand one triangle.

there are 3 angles in a right triangle and because it is a right triangle , you know one of the angles automatically... it is 90 degrees

Answer 14

you should concentrate on the first step, which is a triangle.
