Sum of two angles that are supplementary = 180°
Let the smaller angle be = x


<h3>Their sum :</h3>






Using this let us find the measures of the smaller angle and bigger angle .


∴ The measure of the two angles are = 21° and 159° .
Option B is the odd one out
Call the price of the bike before mark up 'x', then we have:
x + 0.25x = 210
1.25x = 210
x = 168
Therefore, the bike cost $168 before 25% price increase.
