put this solution on YOUR website!To draw this triangle, I recommend you that you take a protractor and measure a 42 degree angle.
You can learn how to use a protractor here: http://www.mathsisfun.com/geometry/protractor-using.html.
Then, after the angle is drawn, be sure to extend the two lines as 3.6cm and 5.2cm. Now, using those endpoints, draw a straight line between them as your third side of the triangle.
