Think of a right triangle. It may help you to draw it.
Start at a point. Draw a point and label it point A. That is where the plane takes off from. Now draw a diagonal segment tilted up to the right and stop at a point and label it B. Segment AB is the path of the airplane. Now draw a segment down vertically to a point you will label C, so that points A and C are on the same horizontal line. Connect points A and C.
You now have a right triangle. Angle C is the right angle. AB is the hypotenuse and is 5.4 km. That is the actual distance the plane traveled. BC is 1.12 km (since 1120 m = 1.12 km) and is a leg of the right triangle. The angle you are looking for is angle A.
For angle A, BC is the opposite leg. AB is the hypotenuse.
The trig ratio that relates the opposite leg to the hypotenuse is the sine.
Answer: 12.0 degrees
Answer: The student enrollment the previous year was 630.
Step-by-step explanation: What we have currently is 504 students which represents 80 percent of the previous total number of students. We can conclude this because the question states clearly that the student enrollment dropped by 20 percent. In other words, we need to add back 20 percent to 80 percent to get the total 100 percent student enrollment from the previous year. The total number of students can be derived as follows;
If 504 equals 80 percent or (0.8), then 504 divided by 4 gives us 20 percent or (0.2)
20 percent times 5 equals 100 percent (or 0.2 times 5 equals 1)
Hence the calculation becomes;
(504/4) x 5 = Total
126 x 5 = 630
Therefore the total number of students enrollment the previous year was 630.
I may be an Ambitious, but due to my absence from Brainly a while back I am no longer an Ace, like I used to be.
Ella has 5 nickels and 7 quarters.
7 quarters is equal to $1.75.
5 nickels is $0.25
$1.75 + $0.25 = $2.00
There are three different choices for the American.
There are 16 different choices for the first non-American and 15 different choices for the other non-American.
So, there are 3 x 16 x 15 different groups.
But, order is important -- who gets the gold, who gets the silver, and who gets the bronze -- there are 6 different ways to arrange the 3 winners (3! = 6).
Thus, there are 6 x 3 x 16 x 15 different results.
