Kindly Answer No. 1st diagram: (ii) In the adjoining figure, find x+y+z+w. Share with your friends Share 0 Neha Sethi answered this Dear student Clearly, z+70°=180° Linear Pair⇒z=180°-70°⇒z=110°Also, y+80°=180° Linear Pair⇒y=180°-80°⇒y=100°and x+130°=180° Linear Pair⇒x=180°-130°⇒x=50°Now consider quadrilateral ABCD,by angle sum property we have,∠ABC+∠BCD+∠CDA+∠DAB=360°⇒∠ABC+130°+80°+70°=360°⇒∠ABC+280°=360°⇒∠ABC=80°Now, ∠ABC+w=180° Linear Pair⇒80°+w=180°⇒w=100°So, x+y+z+w=50°+100°+110°+100°=360° Regards 1 View Full Answer Aryan Goyal answered this SHOW THE DIAGRAM PROPERLY. 0 R.shrinidhi answered this w=70* [corresponding angles are equal.] 70*+a=180* [adjacent angles are supplementary] a=180-70=110* a=110* 70*+z=180*[straight line] z=180-70=110* z=110* 130*+x=180*[straight line] x=180-130=50* x=50* 80*+y=180*[straight line] y=180-80=100* y=100* 0
