Answer:
28.07° ; 70.53° ; 53.13° ; 36.87°
Step-by-step explanation:
Using PYTHAGORAS RULE :
IMAGE 1:
value of cos α equals :
cos α = Adjacent / Hypotenus
cos α = 15 / 17
cos α = 0.88235
α = cos^-1 (0.88235)
α = 28.07°
IMAGE 2:
sin β = Opposite / Hypotenus
sin β = 14√2 / 21
sin β = 0.9428
β = sin^-1(0.9428)
β = 70.53°
IMAGE 3:
From trigonometry :
cot = 1 / tan
Tan = Opposite / Adjacent
Therefore, Cot = Adjacent / Opposite
cot γ = 3/4
cot γ = 0.75
γ = cot^-1 (0.75)
γ = 53.13°
IMAGE 4:
tan α = Opposite / Adjacent
tan α = 15 / 20
tan α = 0.75
α = tan^-1 (0.75)
α = 36.87°
wheres the photo i cant really tell where its at if i cant see it. lol XD
If you can, search for synthetic division calculator and choose the emathhelp one. It shows an amazing, easy to understand explanation!
Answer:
Step-by-step explanation:
From the question we are told that
Angle of elevation 
Height of plane 
Generally the equation for the Distance flown is given by
Therefore Distance flown is
I think it is e because 39 is not even and 48 isnt odd. then a doesn't intersect b when its not 0? I am not sure. But i am pretty sure it is E.
