1.	. ABCD is a trapezium in which AB Il DC. IfZA-4-40Â°, what are the measures of the other twoangles?
Answer» Here the base angles are equal So quadrilateral abcd is isosceles trapezium angle a = angle b angle sum property of quadangle a+ angle b+ angle c+ angle d=360 x+x+80=360 2x=280 x=140 Like my answer if you find it useful!

Answer»

Here the base angles are equal

So quadrilateral abcd is isosceles trapezium

angle a = angle b

angle sum property of quadangle a+ angle b+ angle c+ angle d=360

x+x+80=360

2x=280

x=140
