i’m not from kentucky but it’s A
lmk if you need me to explain
Ashes2049, are you good at geometry?
Answer:
Yes
Step-by-step explanation:
Using Pythagorean theorem WHICH ONLY WORKS FOR RIGHT TRIANGLES,
a^2+b^2=c^2 where a and b are the two shortest legs.
12^2+35^2=c^2
144+1225=c^2
c^2=1369
c=
c=37
<span>P(9,12): For all intents and purposes, the hypotenuse is "r", the opposite side is "y", and the adjacent side is "x".
x = 9 (from the P(9,12))
y = 12 (also from the point)
Using the Pythagorean Theorem, you find out that r = 15.
Therefore, since cos θ = x/r
cos θ = 9/15 or 3/5
Answer: 3/5</span>
Answer:
The center is at ( (-1, -2) and the radius is 5.
Step-by-step explanation:
X^2 + 2X + Y^2 + 4Y = 20
Complete the square on the x and y terms.
(x + 1)^2 -1 + (y + 2)^2 - 4 = 20
(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:
(x - h)^2 + (y - k)^2 = r^2
- the center is at ( (-1, -2) and thr radius is 5.
