The measure of the angles in a parallelogram total 360. Write and solve a system of equations to determine the values of x and y. The parallelogram shows x and 5.5y. The triangle shows x and y. I have the first equation at 180= x + 5.5y. What would be another equation for the triangle?

Question

The measure of the angles in a parallelogram total 360.  Write and solve a system of equations to determine the values of x and y.   The parallelogram shows x and 5.5y.  The triangle shows x and y.  I have the first equation at 180= x + 5.5y.  What would be another equation for the triangle?

carol · Answer

are the angles of x and 5.5y opposite angles or adjacent angles? What do you mean by "the triangle?" Is there a triangle drawn inside the parallelogram?
