A plane flying at a certain altitude is observed from two points that are 2.2 meters apart. The angles of elevation made by the

tan(72)= \frac{y}{x}  ; tan(55)= \frac{y}{2.2 + x}
y=xtan(72);y=(2.2+x)tan(55)
So we are to merge the two equations into one, since both of the equations are equal to y. a = b, b = c therefore, a = c.
xtan(72)=2.2tan(55)+xtan(55)
We are to isolate x.
x[tan(72)-tan(55)]=2.2tan(55)
x=\frac{2.2tan(55)}{tan(72)-tan(55)}
The value of x is approximately, 1.9047m
Then, substitute the value of x from y=xtan(72)
y=1.9047tan(72)
y = 5.862m
Round up, then the answer would be D.

How do you do find a? And how can you tell if it is sin, cos, or tan?

30 60 90 triangle
ratio of short leg : hypo = x : 2x

given short leg x = 4 ft
so hypo a = 2x = 2 * 4 = 8

answer
a = 8 ft
----------------------------------------------
P.S.
if you need to do by using cos sin tan then
Cos (60) = Adj/Hypo = 4/a

a = 4/cos(60) as you know cos(60) = 1/2
so 
a  = 4 /(1/2 = 4 * 2/1 = 8

answer: a = 8 ft
