The area of a Square is 144 because 12x12 is 144 and if both sides are 12 then that equals 144.
Hope this helps!
Answer:
angle: 71
x = -3
Step-by-step explanation:
step 1: 180-(55+54) = 71
step 2: x+74=71 (subtract 74 from both sides)
step 3: x=-3
step 4: -3+74=71
For this case we have that the quotient of 6 and a number, can be expressed as:

Where the variable "x" represents the incognito number.
Now we have that expression is subtracted from 100. Now, we can write the following:

ANswer:
Option A
If the slope of AB = CD and BC = AD it's a parallelogram:
Slope of AB = 6+1 / -9+5 = -7/4
CD = -2-5 / 3+1 = -74
These are equal.
BC = 5-6 / -1 +9 = -1/8
AD = -2 +1 / 3+5 = -1/8
These are also equal so it is a parallelogram.
Now to find if the diagonals are perpendicular find the slope of the perpensicular points:
AC = 5 +1 / -1 +5 = 6/4 = 3/2
BD = 6+2 / -9 -3 = 8/-12 = -2/3
Because BD is the reciprocal of AC, this means they are perpendicular.
And because AB is not perpendicular to AD ( AB and AD are not reciprocals) it is a rhombus.
Answer:
19.10
Step-by-step explanation:
If im correct,
You subtract 10 and 5. Wich is 5. Then multiply that by 3.82.
