The sum of the interior angles of a triangle is equal to 180° so we can write

Solving for y, we get

So the other two angles of the triangle are

and

The error.....Kelvin just figured the 60% markdown cost...not the final price
the final price would be : 30.65 - 0.60(30.65) = 30.65 - 18.39 = 12.26
