Angle Building

Angle Building
A ladder 27 feet long leans against the wall of a building, and the angle between the ladder and the building?

A ladder 27 feet long rests against the wall of a building, and the angle between the ladder and the building is 25 °. (A guess) the distance from the bottom of the stairs of the building. (De the answer to two decimal places.) D =? ft (b) If the distance from the bottom of the stairs of the building increases by 2.0 meters, approximately how far does the top of the stairs move through the building? (Give your answer to two decimal places.) L =? ft

Picture a triangle: ………….. /. | …………. / .. | X = 27 …../…| ……….. Z /….| ………../…..| ………./……| ……. . /*___| ………… and * = 25 ° Then you use SOHCAHTOA. In this case, you need CAH (cosine = adjacent over hypotenuse) calculate the cosine of 25 (sorry, not a calculator) then plug that in this equation: cosine25 = 27 / and Addressed and that is the distance from the bottom of the stairs of the building (also need to resolve SOH: sin25 = z/27 Part b) After finishing (b) not having yy response has come to add 2 to get the new distance. Then you use y ^ 2 + z ^ 2 = 27 ^ 2 to solve the new z. Compare the new to the old ZZY know how far down the building stairs where. not having a calculator at hand, so I can not do the actual calculations, but this is the process that is more useful long term anyway.
