Let the height of the first tower be x, then the second tower is (160 - x) m taller than the first tower. Then
tan 30 = (160 - x)/80
160 - x = 80 tan 30
x = 160 - 80 tan 30 = 160 - 46.19 = 113.8 m
Therefore, the height of the first tower is 113.8 m.
Answer:
127 hamburgers
Step-by-step explanation:
let c = # of cheeseburgers
let h = # of hamburgers
c = 2h (The number of cheeseburgers sold was two times the number
of hamburgers sold.)
h + c = 381 (combined total)
h + 2h = 381
3h = 381
h = 127
8.5 is the nearest one
square root of 72 is about 8.48
rounding to the nearest tenth gives you 8.5

8x+16=32
8x+16-16=32-16
8x=16
8x/8=16/8
x=2
