Using compass directions we simply describe the direction using the angle relative to N, S, E & W.
So in this case, the vector is travelling south west at an angle "41 degrees South of West."
So, when we're tasked with things like this, rewriting everything in terms of sine and cosine and combining fractions often trivializes things, so doing just that gives us:
So out expression is 1/cos(x).
Answer:
18pi or 56.52 if you substitute pi with 3.14
Step-by-step explanation:
W=2L-3
W*L=193
replace W with 2L-3: (2L-3)L=193
2L^2-3L-193=0
Cannot factor
are you sure the numbers are correct?
If it cannot be factored, use the quadratic formula to find out L, then you can find out W
use the Pythagorean theorem to find the diagonal. I don't see an easier way.
