Answer:
The answer is b = √(c² - a²).
Step-by-step explanation:
For right angle triangle, you can apply Pythagoras Theorem where c² = a² + b² .
Answer: P = 25n + 35
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(l +w)
P = 2((8.5n+9) + (4n +8.5))
P = 2(12.5n +17.5)
P = 25n + 35
equation for the perpendicular Bisector of the line segment whose endpoints are (-9,-8) and (7,-4)
Perpendicular bisector lies at the midpoint of a line
Lets find mid point of (-9,-8) and (7,-4)
midpoint formula is


midpoint is (-1, -6)
Now find the slope of the given line
(-9,-8) and (7,-4)


Slope of perpendicular line is negative reciprocal of slope of given line
So slope of perpendicular line is -4
slope = -4 and midpoint is (-1,-6)
y - y1 = m(x-x1)
y - (-6) = -4(x-(-1))
y + 6 = -4(x+1)
y + 6 = -4x -4
Subtract 6 on both sides
y = -4x -4-6
y= -4x -10
equation for the perpendicular Bisector y = -4x - 10
