Answer:
35 degrees.
Step-by-step explanation:
In order to find an angle in a triangle we need to know the other two angles, because the angles in a triangle all add up to 180 degrees. So, knowing two will get us the other one. In this case, we know two angles. One of them is 55, and the other, since it is a right triangle, is 90. So the two angles we know are 55 and 90. Using that all angles in a triangle add up to 180, we can use
55 + 90 + x = 180
145 + x = 180
x = 35

Well i could tell you if you attach a picture :)
The slope is the ratio between the change in the y and x values. When you write a line as 
, the slope is the coefficient 
. So, the slope of the first graph is 405, which means that the first plane flies with a speed of 405 miles per hour.
Similarly, from the table we can see that each time you increase x by 1, the distance traveled increases by 435. So, the slope of the second graph is 435, which means that the second plane flies with a speed of 435 miles per hour, and is thus faster.
31.25% of the population is under 25 years of age. To figure this out, divide 20,000 by 64,000. Then, multiply that answer by 100 to get a percentage. Hope this helps!!
