Answer:
72 ft
Step-by-step explanation:
8 x 9 = 72.
<span>y-10 = -5/4x + 30/4 represents a linear function; we know that because both x and y have the power 1.
We could put this equation into one of several forms.
Suppose we wanted to put it into slope-intercept form. Then </span><span>y-10 = -5/4x + 30/4 becomes y = 10 + 30/4 - (5/4)x, or y = 35/2 - (5/4)x. Thus, this line has the slope -5/4 and the y-intercept (0, 35/2).
If this isn't quite what you wanted, then please share the instructions.

X = 12 y = 5... to get r you'll add 12^2 + 5^2 = r^2. From there you just place the numbers in trig functions.. sin= y/r cos=x/r tan=y/x csc=r/y and so on. If you draw the triangle it's much easier than it looks here.
