Answer

72°

Step-by-step explanation:

sum of angles of a triangle= 180°

Let, the value of the unknown angle in the triangle be y°

Therefore,

30° + 42° + y° = 180°

or,

72° + y° = 180°

or,

y° = 180° - 72°

or,

y° = 108°

We know that a straight line = 180°

here, AM is a straight line (A till the arrow sign of the line is a straight line, you should have named the last point of the line drawn)

Therefore,

y° + x° = a straight line = 180°

we have known before that, y° = 108°

108° + x° = 180°

x° = 180° - 108°

x° = 72°
