How many sides does a regular polygon have if each of its interior angle measures 120 degree​
alekssr [168]
6 sides .

If in a regular polygon, each interior angle = 120 deg, then each exterior angle = 180–120 = 60 deg. So the polygon has 360 deg/60 deg = 6 sides. The figure is a regular hexagon.

Solve for x. Your answer may be in decimal form. Round to the nearest tenth.
drek231 [11]

Answer:

x=54.6

Step-by-step explanation:

Because ΔABC is similar to ΔSTU, we know that their corresponding sides are proportional. Therefore, we know that \frac{AB}{AC}=\frac{SU}{ST}. We are given that AB=x, AC=21, SU=13, and ST=5. After substituting the given values into the proportion and solving for x, we get:

\frac{AB}{AC}=\frac{SU}{ST}

\frac{x}{21} =\frac{13}{5} (Substitute given values into the proportion)

5*x=13*21 (Cross-Products Property)

5x=273 (Simplify)

\frac{5x}{5}=\frac{273}{5} (Divide both sides of the equation by 5 to get rid of x's coefficient)

x=54.6 (Simplify)

Hope this helps!

vladimir1956 [14]

Answer:

The score of Treen is 245 points !!

Step-by-step explanation:

Let the Scored point by Treen be x

<u>Given</u><u> </u><u>:</u><u>-</u><u> </u> Sanjee scored twice as Treen

then, Sanjee Scored is 2x

Also, Cole scored 12 more than Sanjee

i.e., Score of Cole is ( x + 12 )

According to the question ::

The sum of their points is 992

i.e, x + 2x + x + 12 = 992

4x = 980

x = 245

So the points scored by Treen x = 245

<h2><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>Method</u><u> </u><u>!</u><u>!</u><u> </u></h2>

  • Take the unknown value which is to be found as x or any variable

  • Make equations as directed

  • Solve the equation to get the value of x !!
