How many sides does a regular polygon have if one exterior angle is 90 degrees?

2 answers:

5 0

4 sides. Exterior angles add up to 360 degrees, and a regular polygon has equal sides. 360 degrees divided by 90 degrees equals 4 sides.

The polygon will have four sides because the sum of all the exterior angles in a regular polygon is 360 and they all have the same measure so 360/90 = 4

Answer:

Xavier has 5 dollars

Step-by-step explanation:

2x represents how much money Alex had, the -3 is how much he spent, and the 7 is how much he has now

$2x-3=7$

Add 3 to both sides

$2x=10$

divide both sides by 2

$x=5$

Checking my work:

$2*5-3=7\\10-3=7\\7=7$

Convert 3/11 to a decimal equivalent using long division

Anastasy [175]

<span>In order to Convert 3/11 into a decimal, you have to divide 3/11 out. If you were to put the three on top, and the 11 on the bottom, (here's a little tip to make it easier " top dog stays out and snoopy stays in. Top dog would be 3 because it is on the top of the fraction. Snoopy would be the 11 which is on the bottom of the fraction.) so with that being said..... So if you do 3 divided by 11 The answer would be 0.27272727...hope it helped.
