Question

Lines M and N shown below are parallel linesWhat is the valie of x in the measure of the angle?

Answer 1

These two angles are corresponding angles, if you link them with a line, it'll form an F shape, this means that they are congruent.

Since the angles are equal, you can say that

4x-20=84

Now you have a one unknown equation and can calculate the value of x:

`\begin{gathered} 4x+20=84 \\ 4x=84+20 \\ 4x=104 \\ x=(104)/(4) \\ x=26 \end{gathered}`

x=26º
