For this problem you must do Pythagorean theorem:
In this example 10ft is c and 7ft is a (or it could be b, and you'll be solving for a instead of b. It's the same thing, since a and b are both legs)
Plug what you know into the equation:
49 +b^{2} = 100
Bring 49 to the right side by subtracting it:
b^{2} = 51
Now you still must isolate b. The opposite of squaring is taking the square root so take the square root of both sides to cancel it from the left side:
b = 7.1414
b ≈ 7 ft

Answer:
slope of perpendicular line = -
Step-by-step explanation:
calculate the slope m of the given line using the slope formula
m =
with (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (3, 3) ← 2 points on the line
m = =
given a line with slope m then the slope of a line perpendicular to it is
= - = - = -
