Answer:
5x+60 = 360, x = 60
Step-by-step explanation:
Ok, so the key to this problem is to realize that all angles added up in a quadrilateral give you 360 degrees. This means that x+10 + 2x + 2x + 50 = 360. Then we can just simplify to 5x + 60 = 360, 5x = 300, and x = 60.
The answer is 15 cubes with side lengths of 0.5 inches. I did this by adding up all the edge lengths then dividing the answer by 0.5 inches
True. Two lines intersect in a single point.
