Question

plz solve both questions its very urgent

Answer 1

M is a straight line. As we all kn aow that angles on a straight line measure 90°.
Let the angles be x
3x+2x=90°
5x=90°
x=90/5
x=183x=54,2x=36
angle2=angle 6 (corresponding angles)Angle1=angle5
angle1=angle3=angle7(vertically oppositeangles and correspond.ing angles)angle2=angle4=angle8
