Question

1) Outdoor steps generally require larger landings and lower pitches. A particular outdoor staircase climbs a total vertical elevation of 13 feet from the road level to the front entrance of a building. If the angle of elevation is to be 25 degrees and the landing of each step is to be 28 inches, calculate the following. Just need to know how to do it.

Answer 1

this is easier if you draw it

Answer 2

and also remember SOHCAHTOA
Sine=Opposite/Hypotenuse
Cosine=Adjacent/Hypotenuse
Tangent=Opposite/Adjacent

Answer 3

tan 25° = .466

Answer 4

25 degrees

Answer 5

this is for finding a degree

Answer 6

The angle is 25 degrees that is a given I need to know the vertical rise for each step and the total number of steps needed.

Answer 7

finding a side

Answer 8

if you want to know the hypotenuse use Tangent

Answer 9

wait my bad use one of the others NOT tan

Answer 10

Cosine

Answer 11

yes

Answer 12

But wait, if I need to find the height of each step I would have to know the hypotenuse then use the pythagorean theorem. my base squared multiplied by my hypotenuse squared b2+c2=a2
