The answer is 45 degrease
The answer is 0.40 or 0.4
Answer:
in. by 10 in.
Step-by-step explanation:
2 ft by 3 ft, inches is:
2 * 12 = 24 inch
3 * 12 = 36 inch
24 * 36
Thus, to make 36 into 10, we divide 36 by 3.6 to get 10:
36/3.6 = 10
To keep ratio equal, we need to divide 24 by 3.6 to get:
24/3.6 =
Thus, Third answer choice is right.
<span> I am assuming you want to prove:
csc(x)/[1 - cos(x)] = [1 + cos(x)]/sin^3(x).
</span>
<span>If we multiply the LHS by [1 + cos(x)]/[1 + cos(x)], we get:
LHS = csc(x)/[1 - cos(x)]
= {csc(x)[1 + cos(x)]/{[1 + cos(x)][1 - cos(x)]}
= {csc(x)[1 + cos(x)]}/[1 - cos^2(x)], via difference of squares
= {csc(x)[1 + cos(x)]}/sin^2(x), since sin^2(x) = 1 - cos^2(x).
</span>
<span>Then, since csc(x) = 1/sin(x):
LHS = {csc(x)[1 + cos(x)]}/sin^2(x)
= {[1 + cos(x)]/sin(x)}/sin^2(x)
= [1 + cos(x)]/sin^3(x)
= RHS.
