Answer: 540

Step-by-step explanation:

{(n - 2) * 180}

This is the formula for the sum of interior angles with side lengths n. Counting the sides we have 5 sides.

(5 - 2) * 180 = 540

Answer:

\frac{A}{1 + rt}

Step-by-step explanation:

a = p + prt

<u>Distributive property:</u>

A = P(1 + rt)

exis [7]

9514 1404 393

Answer:

  A∩B = {2, 23}

  2 is found in both

  12, 19 are only in set A

  23 is found in both

  29 is only in set A

  34, 40, 45 are only in set B

The intersection of the two sets is {2, 23}.
