Answer:

angle LMN = 67.44°

Area of ΔMNL = 16.66 square units

Step-by-step explanation:

By applying Sine rule in the ΔLMN,

SinM =

SinM = 0.9235

M =

angle = 67.44°

angle of triangle = 180°

67.44 + 38 + angle = 180°

angle = 180 - 105.44

angle= 74.56°

Area of ΔMNL =

= 16.65636093

= 16.66 square units
