1. Draw a line down from that top left corner, perpendicular to the bottom line. 

 

2. That creates a right triangle with hypotenuse = 7 and bottom leg = 3. 

 

3. Use Pythagoras' Theorem to solve for the third side of the right triangle.  

 

4. The answer you got in # 3. is the length of the missing side. 

 

Hint:  It's sqrt(40) but show your work so the teacher will think you did it.
