Answer:
135°
Step-by-step explanation:
Lines L and M are not shown as parallel, but we have to assume they are if we're to answer this question. That makes angle 2 and the one marked 135° alternate interior angles, hence congruent.
∠2 = 135°
_____
<em>Additional comment</em>
Angle 1 = 45° and x = 20.
There are 19 people total, and groups of four are being asked of us. We can use the formula for permutations or combinations.
Permutations:
![\frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D%20)
Combinations:
![\frac{n!}{r!(n-r)!}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%21%7D%7Br%21%28n-r%29%21%7D%20)
Where in both scenarios, there are <em>n</em> objects being chosen at <em>r</em> times.
19 P 4 is 93024
19 C 4 is 3876
It all depends on whether order matters with group placement; if it does, your answer is
93024, if not, then your answer is
3876.:)
