Answer: B : Mean Does Not change
Step-by-step explanation:
Answer:
we know that
Vertical Angles are the angles opposite each other when two lines cross. They are always congruent to one another
in this problem
∠A and ∠B are vertical angles
so
∠A=∠B
we have
∠A=
∠B=
equate angle A and angle B
solve for x
therefore
the answer is
the measure of angle A is
Step-by-step explanation:

The answer is -1.1
Hope you get it right
Find the area of the parallelogram, find the area of the triangle, then subtract the triangle's area from the area of the parallelogram.
Area of Parallelogram:
A= base * height
A= 20 in * 10 in
A= 200 in^2
Area of Triangle:
A= 1/2 base * height
A= 1/2 (10 in)(9 in)
A= 1/2 (90)
A= 45 in ^2
Area of Poster Left:
subtract the difference
A= Parallelogram Area - Triangle Area
A= 200 in^2 - 45 in^2
A= 155 in^2
ANSWER: 155 in^2 is the area of the poster board she has left.
Hope this helps! :)
