0.9x = 450
x = 450/0.9
x = 500
Answer = 500
The answer is the 3rd option
Answer:
50%
the mean (46) marks the halfway point, so over the mean is 50% and under the mean is 50%
Answer:
The angle between the 190 ft. side and the 330 ft. side is 
Step-by-step explanation:
<u>The Law of Cosines</u>
When we know the value of all sides of a triangle, we can compute all of its interior angles by using the Law of Cosines, which is a generalization of the Pythagoras's theorem. If a,b, and c are the known sides of a triangle and
is the angle formed by sides a and b (opposite to c), then

We'll use the values a=190, b=330, c=280 because we want to compute the angle opposite to c
