Answer:
the lines are perpendicular
Step-by-step explanation:
You can tell something by looking at the differences of coordinates:
B-A = (6-2, -11-5) = (4, -16) . . . . . Δy/Δx = -16/4 = -4
D-C = (-1-3, 9-10) = (-4, -1) . . . . . Δy/Δx = -1/-4 = 1/4
The product of the slopes of these lines is (-4)(1/4) = -1, so ...
the lines are perpendicular
Shidddd lil buddy, try the 3rd one
Answer:
D: 25 miles
Step-by-step explanation:
Pythagorean Theorem:
36^2 + b^2 = 39^2
1,296 + b^2 = 1,521
b^2 = 225
b = 25
