Answer: The post office is 32 feet tall.
Step-by-step explanation:
We set up a proportion : 10ft/15ft = xft/48ft
In this equation "x" is the height of the post office. After setting up a proportion with the size of the buildings on the top (numerator) and the shadows of each building on the bottom (denominator) we cross multipy to get our equation to find x. We then divide both sides of the equation by 15 to get our answer.

Answer:
Perpindicular
Step-by-step explanation:
Solve each equation for y, or point Slope form.
y = mx + b
4y = 3x - 4 divide both sides by 4 to isolate the y.
y = 3/4x - 1
The second equation.
4x + 3y = - 6 subtract 4x from both sides
3y = -4x - 6 divide both sides by 3
y = -4/3 - 2
If you visualize line 1 having a Slope of 3/4, that is, for every 4 we move in the positive x direction, y will increase by 3, it slopes up from left to right crossing the y axis at (0,-1). The second line moves 3 in the positive x direction and decreases in y by 4, it slopes down from left to right crossing the y axis at (0,-2}.
Because the two lines have negative inverse slopes they are perpendicular. 3/4x and - 4/3x
