A particular airport has beacons on the ground 6 km out from the start of each runway. An airplane is directly over this beacon and is at an angle of elevation from the runway of 10°.
Calculate the direct line distance from the airplane to the start of the runway

i am sure it will be 90 degrees.

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
