Use the Pythagorean Theorem.
4000^2 + 17000^2 = c^2
16000000 + 289000000 = c^2
305000000 = c^2
c = 17464 miles (B)

Opposite angles are equal, so we know that C=2x and D=5x+5 as well.
The sum of the interior angles of any quadrilateral is 360, so we have

So, the measures of the angles are

Answer:
answer : B
Step-by-step explanation:
(14x2 – 14) + (–10x2 – 10x + 10) = (14x² - 10x²) -10x + (-14+10)
(14x2 – 14) + (–10x2 – 10x + 10) = = 4x² - 10x - 4
answer : B
