Question

The diagram shows a regular polygon.

x
What is the value of x?
Write your answer as an integer or as a decimal rounded to the nearest tenth.

Answer 1

To find the value of x, use the formula

(n-2) x 180, where n is the number of sides.

In this case, we have a TRIangle, which has THREE sides.

So, n=3

(3-2) x 180

1 x 180

180

If the total sum of the angles is 180, then the measure of one angle would be 180 divided by 3, which is 60.
