Question 12 (i)
Find the values of the angles x, y and z in each of the following:

Answer 1

$x={55}^{\circ }Now,{55}^{\circ }+y={180}^{\circ }\text{[Vertically opposite angles]}\Rightarrow y={180}^{\circ }-{55}^{\circ }={125}^{\circ }\text{[Linear pair]}Alsoy=z={125}^{\circ }Thus,x={55}^{\circ },y={125}^{\circ }andZ={125}^{\circ }\text{[Vertically opposite angles]}$
