Quadrilateral</h3>
A quadrilateral is a polygon that has four sides and four angles. The sum of interior angles in a quadrilateral is 360°. Types of quadrilateral are square, rectangle, rhombus, kite and so on.
Let x represent the length of the third side, hence:
x = 5 + (5 * sin(20)) + (5 * sin(10)) = 7.5 cm
The length of the third side of the quadrilateral is 7.5 cm.

3(3x - 8) + 4x = -2(12 - 7x) - x
9x - 24 + 4x = -24 + 14x - x <em>distributed 3 on the left and -2 on the right</em>
- 24 + 13x = -24 + 13x <em>added like terms on the left and the right</em>
<u> -13x</u> <u> -13x </u>
-24 = -24
