How do you find the equation of a perpendicular bisect or of a line segment?

You can take apart the word ‘perpendicular bisector’:

Perpendicular means at a right angle to the line.

So you would find the gradient of your line segment, assuming you were given two points along the line. Then find the negative reciprocal of this gradient to get your new gradient.

Bisector means cut in half.

So you find the midpoint of your line segment.

Now, substitute the midpoint coordinate and your new gradient into the equation of a straight line.

Hope this helps :D

Answer:

c) x = 20, angle COD = 70 °

Step-by-step explanation:

(x+50)° + 90° +20° = 180°

x + 160° = 180°

x = 180°- 160°

x = 20

Angle COD = (x+50)° = (20 +50)° = 70°

What’s The definition of linear and nonlinear in Math

Helga [31]

Answer:

Functions can be classified in two different categories: linear or nonlinear. A simple way to know differentiate between the two is to look at the output values when plugging in a number for an unknown variable. If the output values have a difference that is constant, then the function will be classified as a linear equation; however, if the outputs do not have a constant difference then it will be classified as a nonlinear equation.

Another easy way to determine which of these functions you are dealing with is to graph it. By graphing these functions, you can tell if the line is straight or not. When graphed, a linear equation will have a straight line that has a constant slope. In contrast to this, a nonlinear equation will have a graph that does not have a straight line and, depending on the function, can have many different appearances including a U-shape or an S-shape.
