Given:
Consider the below figure attached with this question.
and
.
To find:
The measure of angle 3.
Solution:
From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.
We know that, vertically opposite angles are always equal. So,






Now,


Therefore, the measure of angle 3 is 140 degrees.
Answer: 100
Step-by-step explanation:
Answer: D. 
Step-by-step explanation:
1. You have the following expression given in the problem above:
÷5
2. By definition, two expression are equivalent when they are the same even though they they are written in a different form.
3. Keeping this on mind, you can rewrite the division of those two numbers as a fraction, as you can see below:

3. Then,
is the equivalent expression to 4h ÷ 5.
Answer:
A total of 720 elk are likely to be infected
Step-by-step explanation:
we shall be using the proportion by survey to estimate the number of infections
From the survey 8 out of 50 are infected. Thus the likelihood of infection is 8/50
We have 4,500 elk to consider. The number of elk likely to be infected will be 8/50 * 4500 = 720
