Step-by-step explanation:
use trigonometry
sin33 =c/17
c = sin33 × 17
use calculator for sin33 becauze I dont know the value sorry for that
it will be around 0.5
Answer:
The correct answer is 10 and 14
PART A
Volume = Area of a triangle base x height (..or length)
Volume = 2,400cm^3
Volume = 1/2(16)(h)(20)
2,400cm^3=1/2(16)(h)(20)
2/400cm^3/160 = 160(h)/160
Part A= 15cm^3=height of the box
PART B
Surface Area = 1/2(15*16)(2)+20(17)(2)+16(20)
Surface Area = 240+680+320
Surface Area = 1,240
Part B = You will need approximately 1,240cm of cardboard.
It wouldn’t be divided by, only because she’s not sharing it among 3 different people.
Instead I would write x - 3 because you’re taking away 3 candy bars.
