Answer: x=9
Step-by-step explanation:
The bottom triangle that has a 40° is an isosceles triangle, therefore the other angle at the bottom right is also 40°. This leaves the top angle to be 100°.
180=40+40+x
180=80+x
x=100
Now, to find ∠2, you can tell it is a supplementary angle. Therefore, the 2 angles add up to 180°
180-100=∠2
80°=∠2
The problem states that ∠2 is 9x-1. We know that ∠2 is 80°. We can solve for x.
80=9x-1
81=9x
x=9
The answer is 1/4, there are 4 options and the baseball cards are one selection.
D) 72 units, you get this answer by adding up 15+15+22+20 units to get the perimeter.
The area of carpet square is 81 square inches
<h3><u>Solution:</u></h3>
Given that carpet squares has sides that are 9 inches long
<u><em>To find: area of carpet square</em></u>
Since given that carpet is of square shape, we can use area of square formula
<u><em>The area of square is given as:</em></u>

Where "s" is the length of side
Given s = 9 inches
Substituting the values in above formula, we get

Thus the area of carpet square is 81 square inches
