Answer 4

Exactly. I figure \(\sqrt{11^2+7^2}=13\) and 13:7::200:x

Answer 5

\[\frac{7}{13}=\frac{x}{200}\]\[x=107N\]
Does that seem right?

Answer 6

In fact i did'nt get this rule... i had solved the examples by resolving the force vector in their components..

Answer 7

@Loser66 is this right?

Answer 8

I don't get it either
