Answer:
12/13
Step-by-step explanation:
We know that cosine is the adjacent side divided by the hypotenuse in a right triangle.
The adjacent side to angle C is BC
The hypotenuse is AC because it is opposite to the right angle
So...
cosine is (BC)/(AC)
36/39
12/13
Answer:
A
Step-by-step explanation:
Formula is y=(x-h) Where h is the number the function is moved left or right...since it is supposed to be moved right, then (x-9) should probably work
x^2 = 81/100
Let's take the square root of each side
x = 0.9 and -0.9
X>Y
X=7Y
3X=7+4Y
X=?
Y=?
----------------------------
3*7=7+4Y
21Y=7+4Y
21Y-4Y=7
17Y=7
Y=7/17
----------------------
X=7*7/17
X=49/17
