An airplane bas begun its descent for a landing. when the airplane is 150 miles west of its destination, its altitude is 32,000 feet. when the airplane is 100 miles west of its destination, its altitude is 14,000 feet. if the airplane's descent is modeled by a linear function, where will the airplane be in relation to the runway when it hits ground level?
a) airplane will over shoot the runway by 61 feet
b) airplane will over shoot the runway by 610 feet
c) airplane will land short of the runway by 61 feet
d) airplane will land short of the runway by 6.1 feet

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
