80/cos(55)=x
Answer:

Step-by-step explanation:
Since we're looking at perpendicular lines, the slope of the new line is the reciprocal of the original line.
So the slope of our new line is 
So far, we are looking at 
Now we need to find the b value by plugging in the given point.

So the final equation is 
The equation of the line is y = -2/3(x) - 4
8 times 8 so 64 is your answer :) hope this helps
