Answer:
8792mi^2
Step-by-step explanation:
basic area calculations width times length
Let the height of the three be h and the distance between student A and the tree be x, then
tan 57 = h/x
x = h/tan 57
tan 46 = h/(x + 1)
x + 1 = h/tan 46
h/tan 57 + 1 = h / tan 46
h / tan 46 - h / tan 57 = 1
h(tan 57 - tan 46) = tan 46 tan 57
h = tan 46 tan 57 / (tan 57 - tan 46) = 3.2 yards
Best way I can explain it is $2 for X, X is amount of sandwiches she sold, $3 for every Y, Y is the amount of wraps she sold, 1 month she made $1,470
therefor 2x + 3y = 1,470
