Answer:
P = 36 inches
A = 81 inches ^2
Step-by-step explanation:
This is a square so all the sides lengths are equal
P = 4s where s is the side length
P = 4*9 = 36 inches
A = s^2 where s is the side length
A = 9^2 = 81 inches ^2

Here, sum of all the angles would be equal to 360.
We can see there are two right angles (=90)
So, 90 + 90 + x + 60 = 360
240 + x = 360
x = 360 - 240
x = 120
In short, Your Answer would be 120
Hope this helps!
Answer:
Choice B. False. Rather, the opposite angles of a circumscribed quadrilateral are always supplementary with a sum of 180 degrees.
Step-by-step explanation:
Refer to the sketch attached.
Consider the quadrilateral ABCD inscribed in the circle O. Angle 
is the angle that line BA and DA inscribe. The green angle at O will be the arc that the two lines intercepts. Let angle A equals 
degrees. By the inscribed angle theorem for circles, The green angle will measure 
.
Similarly, the arc that line CD and CB intercept will equal to twice the measure of 
. The angle of that arc is the red angle at the origin. The value of that arc will equal to 
.
Angle 
is half the measure of that arc. That is:
.
Note that 
. The sum of A and angle C is 180 degrees. In other words, the two angles are supplementary. The claim that the two angles are complementary (which describes two angles with a sum of 90 degrees) will thus be false.
The smaller the MAD, the closer the data points are together
