Answer:
23.7
Step-by-step explanation:
Yes, because if you have x=5 and x=10 they are parallel lines to each other.
No, because the sum of the measures shorter legnths of the sides must be greater than the measure of the greatest angle
4+8=12
so therefor the side legnths if you tried to make into a triangle, it would make a line 12 units long
