Answer:
Step-by-step explanation:
There are two ways to do this.
1. You could make an accurate diagram and measure R. This works but the computer won't like it. However you will know if you are correct. An answer ± 2 degrees would tell you that you are likely correct.
2. The second way is to find <C. Similarity guarantees that <C and <R are equal. The adjacent side to angle C is the second longest line. The second longest line in PQR is the adjacent side of <R.
Naturally we will use the second method, but you ought to try the first method. It's cumbersome but it will teach you how to read the values of triangles to make clear the trig functions.
Tan(C) = opposite over adjacent
Tan(C) = 7 / 9
Tan(C) = .77777777...
<C = tan-1(0.7777777...)
<C = 37.87
<C = 37.9
Answer:
She donated b/50 books
Step-by-step explanation:
In this question, we are we are told 150 students donated a total of b books. The average number of books donated by each student will be:
The total number of books/ the total number of students.
The average number of books is this b/150.
Now, we are also told that Hannah donated 3 times the average number of books.
This is simply calculated by multiplying the average number of books donated by 3
This is equal to 3 * b/150 = b/50 books
Hence, Hannah donated b/650 books
Answer:
13 and 16
Step-by-step explanation:
The coefficients are the numbers that are next to a variable. In the expression:
13a+16b
Both 13 and 16 are next to a variable. Therefore, 13 and 16 is the correct answer.
