    corresponding sides of the 2 triangles are in the same ratio identify which angles are equal in order to determine corresponding sides

    Try again! < BAD = < ACD ( because they both make a right angle with < CAD)

    right because 5 and x are corresponding sides

    now angle ABD and CAD are equal so their corresponding sides can be written as a fraction also

    no we need another 2 sides to form an equation one from small triangle ( which will be in numerator) and one from larger trianglw)

    right so we have 5 / x = x /9 solve for x
