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

lana [24]

$tan(72)= \frac{y}{x} ; tan(55)= \frac{y}{2.2 + x}$
$y=xtan(72);y=(2.2+x)tan(55)$
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.
