Answer:
The length of AM is 26.50 units.
Step-by-step explanation:
Given information: AB = BC, BM = MC
, AC = 40, ∠BAC = 42º.
Since two sides of triangle are equal, therefore the triangle ABC is an isosceles triangle.
The corresponding angles of congruents sides are always equal. So angle C is 42º.
According to the angle sum property the sum of interior angles is 180º.

Law of Sine






Therefore the length of AB and BC is 26.91.
Since M is midpoint of BC, so

Use Law of Cosine in triangle ABM to find the value of AM.




Therefore the length of AM is 26.50 units.
