It is to be remembered that a a pentagon has five sides. First, we determine each of the central angles by dividing the given sum (360°) by 5. This gives us the answer of 72°. If we let x be the congruent angles in the base and noting that the sum of the internal angles of the triangle is 180°, we have the equation,
72 + x + x = 180°
The value of x from the equation is 54°.
Answer: 72/20 = <u>3 3/5</u>

Answer:
24.2 feet.
Step-by-step explanation:
pythagorean theorem will solve this so A^2 + B^2=C^2
we have a and c so you do c -a and square root it to get your answer
Answer:
90v - 80
Step-by-step explanation:
-10 ( -9v + 8 )
Distributive property (multiply what is in the parenthesis by -10)
-10 * -9v + -10 * 8
90v - 80
2 negatives become a positive
