We know that
in the right triangle
<span>sinθ=opposite side/hypotenuse
</span><span>cosθ=adjacent side/hypotenuse
</span><span>tanθ=opposite side/adjacent side
in this problem
opposite side angle </span>θ=8
adjacent side angle <span>θ=15
hypotenuse=17
so
</span>sinθ=8/17
cosθ=15/17
tanθ=8/15
A. Y= -7
X=2
4x+2y=-6
+(3x-2y=-8
(x^2-5)(3x-1)
Here's how I got this answer:
I found the GCF for each part of the polynomial.
3x^3 and -15x both contain 3x, and -x^2 and 5 share -1.
I then can divide the polynomial by 3x-1, and I get x^2-5
(Okay, that's not what I really did, but I can solve these on sight and don't remember the proper way to do it.)
