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

answer:

step-by-step explanation:

the sum of the measures of the exterior angles of a shape is always 360 degrees.

so we are looking for a shape that has 360 degrees as the sum of the interior angles.

can't be 4) because a triangle has 180 degrees.

can't be 1) because a hexagon has 720 degrees.

can't be 3) because a pentagon has 540 degrees.

what about 2)? a quadrilateral has 4 sides so a square or rectangle are both possibilities (amongst others). both squares and rectangles have 4 right angles (four 90 degree angles). 4 x 90 = 360

answer:

a 5-sided shape or pentagon

step-by-step explanation:

540 degrees is signature of a pentagon (a 5-sided figure)

i don't see a pentagon out of these three pictures but it seems as though there might be a shape above it?

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
