You can factor it out :)
4x+12=4(x+3)
200 times 20 qnd ten then 30 if you want then go from there
<span>slope formula, which states that m = (y2 -- y1) / (x2 -- x1).</span>
Answer:
The solution is (18,21)
Step-by-step explanation:
The picture shows the steps.
Hope this helps!!!
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) =
