Answer:
Circle = 7
Pentagon = 8
Square = 12
Square + Square + Square = 36
Step-by-step explanation:
Since you know the circle is 7, the square plus the pentagon must be 20. That means the pentagon in the third equation is 8. This means the square is 12.
So, 12 + 12 + 12 = 36.
Answer:
54.8
Step-by-step explanation:
Pythagorean theorem is a^2+b^2=c^2.
Plug the given values in to get 61^2+b^2=82^2
61^2 is 3,721 and 82^2 is 6,724.
6,724-3,721 is 3,003.
The square root of 3,003, rounded to a reasonable value, is 54.8.
The length of AC is 54.8.
This is the answer with the correct work.
The answer is Commutative Property.
