Answer:
About 14.8 ft
Step-by-step explanation:
This is a triangle. A man walks one direction, turns, and walks another direction. The question asks for you to find the distance, which is the hypotenuse side. This makes our triangle (see attachment 1)
Since this is not a right triangle, we will use law of cosines.
We are given 2 sides and an angle. However, 20 degrees is the exterior angle. To find the interior angle (green theta), we have to do a calculation:
180-20=160 degrees. This is green theta.
Now, we have all we need to use law of cosines. (see attachment 2)
Answer:

Step-by-step explanation:
Given


Required

Since the events are mutually exclusive, then:

So, we have:

Take LCM



Answer:
1) at ( 0,0) : y = x/2. at(-3-1) : y = -1. at(-3,3) : y = 2x +9

Answer:
A 0.01
Step-by-step explanation:
<em>I saw the answer on the internet.</em>
-3/4 goes between -1 and 0 it is the 3rd line to the left and n would go between positive 0 and 1 on the 3rd line to the right
