Question

in the figure below AB and CD are parallel calculate all other angles in the figure.​

Answer 1

Angle C = 30° { Since AB and VD are parallel to each other ( Alternate Interior Angles ) }

Angle D = 70° { Using same property }

Use Angle sum property of a triangle i.e.,

In ∆ABE,

Angle A + Angle B + Angle E = 180° {since sum of the angles of a triangle u 180°}

Using this properties you'll get to solve this sum.
