Answer:
Step-by-step explanation:
If the upper triangle has a right angle at Island C, we need only use the Pythagorean Theorem to find x:
(10 mi)^2 + (20 mi)^2 = x^2, so that
x^2 = 100 mi^2 + 400 mi^2 = 500 mi^2, which reduces to
x = +10√5 mi
Note that the shortest side (10 mi) is adjacent to a 30 degree angle. Thus, the upper triangle is a 30-60-90 triangle, meaning that the Pythagorean Theorem DOES apply here.

Answer:
c) 700
Step-by-step explanation:
Add 800 and 600, and then divide by the number of number, or in this case, two. This should give you 700.
Answer: hey im not sure, but i think your supposed to solve 7x-6 and 9+12x. Add these two together and times it by 55. Im not syre if this is right but u could try it.
<span>Five Thousand ones equals Fifty hundred ones; this can be understood by moving the numerical comma on place 5,000 becomes 50,00; to change the notation you can also divide 5,000 by 100 which equals 50. Therefore it equals 50 hundred ones. By simple division you can arrive at the answer for this.</span>
