Answer:
A. subtract s: -7, -10, -13
Step-by-step explanation:
Tan=z/10 and cos=10/y from cos we know the hypotenuse is y. from tan we know the opposite side is z
So sinx=z/y
A perpendicular slope is a slope that is the negative reciprocal of the current slope. Therefore, 3.
What are the coordinates of the points of tangency? Yes, it's *that* trivial.

(1) it is (C) the commutative property of multiplication: a*b = b*a, so 2*(-6/7) = (-6/7)*2
(2) it is (D) the commutative property of addition: a+b=b+a, so 5*4+3=3+5*4
commutate = "swap around"
