What is the sum of the measures of the interior angles of a regular polygon if each angle measures 72

540 degrees.

Step-by-step explanation:

I assume that 72 degrees is the measure of  an exterior angle. This is the case in a pentagon because 360 / 72 = 5.

So each interior angle measures  180 - 72 = 108 degrees.

The sum of the interior angles = 5 * 108 = 540 degrees.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
