Question

A polygon has n sides. Two of its angles are right angles. Each of the remaining angles equal to 150 degrees. calculate n. Please help! =)

Answer 1

The variable n represents a number of sides polygon has.

We know that all polygons have a total angle of 180(n-2).
Triangle - 180º
Square - 360º
Pentagon - 540º
Hexagon - 720º
\(\vdots\)

Now, we know this polygon also has two right angles and remaining angles is 150º
90(2) - 150(n-2)

Now set it equal to 180(n-2).

180(n-2) = 90(2) - 150(n-2)

Now find n.

Does this make sense?
