<u>Answer</u>
12
<u>Explanation</u>
Cosine is the ratio of adjacent to hypotenuse.
So, in this case b is the adjacent and 13 is the hypotenuse.
cos22.6 = b/13
b = 13×cos22.6
= 13×0.923879532
=12.010
To the nearest whole number the answer is 12.
Answer:
B'(-5,-6)
Step-by-step explanation:
The mapping for 180° clockwise rotation about the origin is:

The find the image of B(5,6), we plug in x=5 and y=6 into the rule.

Therefore the coordinates of B' are (-5,-6).
Answer:
n=54
Step-by-step explanation:
Since this is a proportion problem, you have cross mulitply.
7n=9x42
7n=378
n=54
