Question

Find the value of x ,y and z​

Answer 1

`\mathrm{(i)\ }x+45^o+75^o=180^o\ \ \ [\mathrm{Sum\ of\ angles\ of\ triangle\ is\ 180^o.}]\\\mathrm{or,\ }x+120^o=180^o\\\mathrm{or,\ }x=60^o\\`

`\mathrm{(ii)\ }x=y=60^o\ \ \ [\mathrm{Alternate\ angles.}]\\\mathrm{(iii)\ z=45^o}\ \ \ [\mathrm{Alternate\ angles}]`
