Question

The adjacent figure HOPE is a parallelogram. Find the angle measure x, y and z. State the properties you use to find them.

Answer 1

first property =supplementary angles

therefore E = 180-70

=E=110°

second property= adjacent angles are supplementary

therefore, 40+Z+110=180

=Z=180-40-110

=Z = 30°

third property = angle sum property of a triangle

therefore 30+110+Y=180

=Y=180-140

=y=40°
