Please help me undertsand this question.

So basically, you want to show why the two lines (m and n ) are the "same". To show this you would say <4 &<5 are also supplementary because it is the same as <3 & <6. I think this is what the question is asking. To prove this you use the Converse Theorem. Which is what I just showed you with the angles.

Answer:

See below.

Step-by-step explanation:

It is the one at the top left side.

The line y = x passes through the origin at an angle of 45 degrees to the x axis and rises to the right.

So if you imagine its a mirror you'll see that its a reflection in that mirror.

Does anyone know how to solve this?

Answer:

$x=360$

Step-by-step explanation:

The inscribed angles theorem states that when given a circle, with an angle that has its vertex at the center of the circle, the measure of the angle is congruent to the measure of the arc surrounding it. One can apply this knowledge here by stating the following,

$m$

Substitute,

$x=2\pi$

However, this answer is in radians, it is the literal measurement. One must convert into degrees so that the answer fits the format of the question. The conversion rate to switch between radians and degrees is the following,

$degree=\frac{\pi}{180}radians$
