[UKMT] If a n-sided polygon has exactly 3 obtuse angles (i.e. 90° < 0 < 180°), the rest acute or right-angled, then determine the possible values of n (Hint: determine the possible range for the sum of the interior angles, and use these inequalities to solve).

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
