The sum of the interior angles of a polygon with sides is
Since a pentagon has 5 sides, the sum of its interior angles is
Since it is a regular pentagon, all sides and angles are the same, so one single angle measures
degrees.
Start by dividing both sides by 2 to get
. Doing the math on the right, keeping in mind that logs have an unwritten base of 10, gives us
. Rewriting this in exponential form is
. That means that x = 8. Not negative, only positive.
Answer:
Step-by-step explanation:
6x + y = 30
-6x - 15y = 54
-14y = 84
y = -6
6x - 6 = 30
6x = 36
x = 6
(6, -6)
Answer:
C
Step-by-step explanation:
Answer: 14 feet
Step-by-step explanation: the difference between the shadow of the building and the building is 4 feet so the difference between the shadow of the statue and the statue is 4 feet so the answer is 14 feet.
