cos is . So, if cos(a)= then use Pythagorean Theorem to determine the length of the "opposite" side.
5² + x² = 13²
25 + x² = 169
x² = 144
x = 12
Now that you know the length of the opposite side, you can plug it in for sin.
sin is . So, sin(a) =
Now, if you switch so you are looking for sin(b), the cos and sin also switch.
cos(b) = sin(a) =
sin(b) = cos(a) =
Answer: sin(b) =
Answer:
(-1, -6)
Step-by-step explanation:
f(x) = x - 5
f(x) = -1-5
f(x) = -6
(-1, -6)
Answer: JL=10x+12
Step-by-step explanation:
JL=JM+ML
JL=8x-21+2x+33
JL=8x+2x-21+33
JL=10x+12
==> I noticed that to draw a B or a D, you have to use both straight and curved lines. Maybe that's the pattern.
Hold up, hee haw, whoa ! There are no curved lines, only straight ones, in F and H. That can't be the pattern.
==> I noticed that to go from B to D in the alphabet, you skip one letter (C). Maybe that's the pattern.
Well Hyola ! If you skip one letter in the alphabet each time, you can get from D to F, and then from F to H, and then from H to J .
I'm willing to go out on a limb, bet 3¢ , and state my conjecture that the pattern is "To get from one term to the next term, skip one letter in the alphabet.".
I can't be absolutely positive and say "That's definitely it !". There may be other patterns that can produce the same 5 letters but then not work after that. But the pattern of "Skip-one" can produce these 5 letters, so it's a reasonable conjecture.
$300 income
$250 + $100 = $350 expenses
$300 - $350 = a loss of $50
