Here is the question you're asking, and its answer.
Answer:
618 birds.
Step-by-step explanation:
Let the estimated number of birds=x
Out of x birds, he tied a belt around the legs of 40 birds.
When he observed 520 birds, 34 of which had belts.
Expressing each as a ratio

Cross Multiply
34x=520X40
x=520X40÷34=611.7≈618
There are an estimated 618 birds.
9, -12, 24
The zeroes are the numbers in the parentheses with the opposite signs (-9 becomes 9, 12 becomes -12, and -24 becomes 24)
We are asked to complete the following statements about the graphed angles:
Question a)
angle 1 congruent to _______
Notice that angle 1 in the image is opposite via the vertex to angle 3.
Amgles opposite via the vertex are always congruent (equal in magnitude) to each other. So, we complete the blank by typing angle 3. These are called "opposed by the vertex" angles.
Question b)
Angle 4 is congruent to angle _______ and they are called are called ______ angles
Angle 4 is congruent to its opposite by the vertex angle (which is angle 2. So we complete the first blank with the number 2.
The second blank is exactly as for the first case, that is "opposite by the vertex".
