An
amusement park ride has a moving platform attached to four swinging arms. The
platform swings back and forth, higher and higher, until it goes over the top
and around in a circular motion. In the diagram below, AD and BC represent two of the swinging arms, and DC <span>is parallel to the ground
</span>(line l). Explain
why the moving platform AB <span>is always parallel to the ground.</span>

Riaz : Ali
3 : 2
Add the two values; so 3 + 2 is 5
Then 100/5 = 20
So: 20 x 3 = 60
and 20 x 2 = 40
Riaz = 60%
Ali = 40%
Then write 60% and 40% as a fraction:
60% = 3/5 (3 over 5)
40% = 2/5 (2 over 5)
