Two airplanes leave an airport. Thirty minutes later, an observer on the ground sees the first plane with an angle of elevation measuring 56° and an altitude of 9,000 m. At the same time, the second plane has an
angle of elevation of 36° (in the opposite direction) and an altitude of 10,000 m. Find the air distance between the two planes, rounded to the nearest kilometre. Draw a picture to help you solve. [4]

brandon has 4344 video games.  

step-by-step explanation

7373 - 2929 = 4344

pls let me know if it was correct

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 .

i believe b is the answer
