Explanation / Answer

   Given :              h/w= heightof mirror/width of mirror hw/ww = height of window/ width ofwindow = 0.30m/1.3m xe/xw = distance of eye/ window frommirror = 0.67m/1.50m tanver = h/xe =hw/ xe+ xw    or h = hw xe/xe+xw substitute the values for h we get the heigth of mirror tanhor = w/xe =ww/xe +xw or w = ww xe/xe +xw substitute the values for w we get the width of mirror    I hope it helps you h/w= heightof mirror/width of mirror hw/ww = height of window/ width ofwindow = 0.30m/1.3m xe/xw = distance of eye/ window frommirror = 0.67m/1.50m tanver = h/xe =hw/ xe+ xw    or h = hw xe/xe+xw substitute the values for h we get the heigth of mirror tanhor = w/xe =ww/xe +xw or w = ww xe/xe +xw substitute the values for w we get the width of mirror    I hope it helps you
