A+ Series - Core Mathematics THEORY QUESTIONS Question 1 (SSSCE 2000 Ou 12a) Four angles of a hexagon are 130°, 160°, 112° and 80°. If the remaining angles are equal, find the size of each of them ​

To solve this question, we have to understand the sum of all angles of a polygon, identify the polygon and doing this, we get that the size of each of the angles are: 119º.

Sum of angles:

The sum of angles of a polygon of n sides is given by:

Hexagon:

6 sides, thus , and:

Angles:

Four are 130°, 160°, 112° and 80°, the other two are equal, so both are x. Then:

Thus, the size of each of them is of 119º.
