Answer:
c) 12/15 = 4/5
Step-by-step explanation:
imagine we mirror the triangle up, so that Z is on top.
then you can clearly see that 6 is cos(X) times r (and r is then 7.5).
XY is sin(X)×7.5
and again, 7.5 is r (the line making the X angle).
so, the cosine ratio of X is
6 = cos(X)×7.5
cos(X) = 6/7.5 or then 12/15. or simplified 4/5.

Answer:
y =
x -4
Step-by-step explanation:
The slope-intercept form of an equation of a line is given by:
y = mx + b, where m = slope and b = y-intercept
Given the slope and point on a line, you can solve for 'b' in the equation:
(3, 3) - x = 3, y = 3
slope = 
Plug into the equation:
3 =
*3 + b
3 = 7 + b
-4 = b
y =
x - 4
