Math
The inside has to equal 360 since its a 4 sided figure you know 2 sides which are 90 and the third side is 52 so 360= 52 + 90 + 90 + x solve for x 360 - 90 - 90 - 52 = x x=128
March 22, 2012

math
multiply both sides by 5 to get rid of the denominator and you get w(5)/5 = 6( 5) the 5's cancel out on the left side and you get left with w= 30 ** always remember - whatever you do to the left side you must do to the right* ( in this case we multiplied left side by 5 so ...
