<span>The sum of the interior angles of any regular polygon is (n - 2) X 180
30 = n
</span><span>[(30) - 2] × 180
</span>28 X 180
5040

<span>The interior angle of a regular polygon = the sum of interior angles ÷ number of sides</span>
5040 <span>÷ 30 = 168</span>

Therefore the measure of each interior angle in a regular 30-sided polygon is 168°

The width of a rectangle is 8y- 1.5 feet and the length is 1.5y+9 feet. Find the perimeter of the rectangle.

lyudmila [28]

Answer:

$P=19y+15$

Step-by-step explanation:

Step one:

Given data

dimension of the rectangle

Width = 8y-1.5

Length = 1.5y+9

Required

The expression to represents the Perimeter

Step two:

the perimeter of a rectangle is expressed as

$P= 2L+2W\\\\P=2(1.5y+9)+2(8y-1.5)\\\\P=3y+18+16y-3\\\\$

collect like terms

$P=3y+16y+18-3\\\\P=19y+15$
