Answer:sqrt65
Step-by-step explanation:
Distance formula d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}
<span>The square is equal so all sides have equal sides. Soooo...
s2 (s squared) + s2 = 15 (squared)
15 x 15 = 225
225/2 = 112.5
Now you just have to get the square root. So go onto ur calculator. Which equals 10.606

Parallel lines will have the same slope
y - y1 = m(x - 1)
slope(m) = 1/4
(5,5)...x1 = 5 and y1 = 5
now we sub
y - 5 = 1/4(x - 5) <==== ur parallel line
==================
perpendiculr lines will have a negative reciprocal slope. To find the negative reciprocal, u flip the number and change the sign. So the negative reciprocal of 1/4 is -4....see how I flipped 1/4 and made it 4/1...then changed the sign making it -4/1 or just -4. That will be ur slope of the perpendicular line.
y - y1 = m(x - x1)
slope(m) = -4
(5,5)...x1 = 5 and y1 = 5
now we sub
y - 5 = -4(x - 5) <=== ur perpendicular line
