Answer 2

Answer:

$3y=x+15 \\  [corresponding angles] \\ </p><p></p><p>And, x+15=2y+25 \\  [Vertically opposite angles] \\ </p><p></p><p>Therefore, \\ </p><p></p><p>3y=2y+25 \\ </p><p></p><p>y=25o \\ </p><p></p><p>$

$Now,  \\ </p><p></p><p>x+15=2y+25 \\ </p><p></p><p>x+15=2(25)+25 \\ </p><p></p><p>x+15=75 \\ </p><p></p><p>x=60o \\ </p><p></p><p>$
