  3. Cut two intersecting lines through your cookie. What do you notice about the opposite angles?Write a conjecture Draw a picture ____________________________________________ ____________________________________________ ____________________________________________ _____________________________________________ Vertical angles ___________________________________________________________________ W As shown in the diagram, XY and WZ intersect at E. If m<XEW is represented by 2x + 40 and m<ZEY by 6x – 20, find the measure of m<XEZ x E Y Z The measure of two vertical angles are represented by 3x – 10 and x + 30, find the value of x. AB and CD intersect at E. If m<CEB is represented by 5x – 8 and m<AED is represented by x + 36, find the value of x.
