Class 8 chapter number 3 exercise 3.3 question number 7
Q7 :
The adjacent figure HOPE is a parallelogram. Find the angle measures x, y and z. State the
properties you use to find them.
Answer :
y = 40° (Alternate interior angles)
70° = z + 40º (Corresponding angles)
70° - 40° = z
z = 30°
x + (z + 40º) = 180° (Adjacent pair of angles)
x + 70º = 180°
x = 110°
