For which polygon is the sum of the interior angles equal to 540?

Pentagon

Step-by-step explanation:

to find the sum of the interior angle, use the equation sum=180(n-2) degrees, with the number of sides being n

sum= 180(5-2) degrees

sum= 540 degrees

correct answer:

i^31 = -i

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
