Question

answer the fifth one

Answer 1

triangle LMN is congruent to triangle DEF
Therefore angle M = angle E and
angle N = Angle F....by govt
angle M = angle M....given
therefore angle M = angle N = Angle D = angle F
angle D =55
hence angle M = angle N = 55
in triangle LMN angle M + angle N + Angle L = 180
55 + 55 + angle L = 180
angle L = 70
therefore angle MLN = 70
