Step-by-step explanation:
area= length x width = 9x4
Answer:
Vertically opposite angles
Step-by-step explanation:
Given

What else can measure 
The question has missing options. So, I will give a general explanation.
Using the attached image as a point of reference.
Given that:

The value of b is calculated as:

Because b and
are vertically opposite angles
<em>This gives:</em>
<em></em>
<em></em>
<em></em>
<em>So, one possible answer to the question is a vertically opposite angle</em>
<h3>
Answer: 30.78181 meters</h3>
The value is approximate. Round that however you need to.
========================================================
Explanation:
- lowercase a = side opposite angle uppercase A
- lowercase b = side opposite angle uppercase B
- b = AC
Using the law of sines, we can say:
a/sin(A) = b/sin(B)
45/sin(30) = b/sin(20)
b/sin(20) = 45/sin(30)
b = sin(20)*45/sin(30)
b = 30.78181 approximately
You'll need to make sure your calculator is in degree mode.
B because .06 + .12 = .18 which is 18% out of 250 people
