    ABCD is a rectangle. Find the length of each diagonal. AC=2(x-3) BD=x+5

    AC and BD are the diagonals, and diagonals of a rectangle are equal to each other 2(x-3) = x + 5 the first step is to solve for x, can you do that for me please?

    first, look at the left side of the equation 2(x-3) distribute the 2 and tell me what you get

    right! so the left side of the equation is 2x - 6 and the right side of the equation is x + 5 2x - 6 = x + 5 can you try solving for x now?

    add 6 to both sides, since we have -6 on the left side and we want to get rid of it

    right, x = 11, only one more step to go! let's use the equation from before, BD=x+5 if x = 11, what is x + 5?

    not quite :) we have to solve for "Y" when given 3y + 6 = 90 you would first subtract 6 from both sides

    ohhhh then it should definitely be a ... rhombus or something and the diagonals of a rhombus always bisect at 90 degree angles so if it really is a rhombus, then it should be 90 degrees ^_^

    assuming angle 1 equals angle 2 there are 360 degrees in a quadrilateral 360 = 2*104 + 2*(2[angle 1]) 360 = 208 + 4 [angle 1] now subtract 208 from both sides
