Answer:
Step-by-step explanation:
The middle line is the median, then from left to right the lines are the first, second, third and fourth quartile.

There's no solution in the set of real numbers.
The answer is 43. You have to do: 180 (maximum in the triangle) - 47 - 90 (the angle that isn’t x) = 43. That’s the measure of x!
45x20x18=16,200
350x9=3150
total = 19,350
