Answer 2

Answer:

$arc\ MN + 150 = 180$

Step-by-step explanation:

Given

$\angle NOP = 150^\circ$

See attachment for circle O

Required

Find $arc\ MN$

The sum of angles in a semi-circle is 180 degrees.

So:

$arc\ MN + \angle NOP = 180$

This gives:

$arc\ MN + 150 = 180$

Hence, the equation is: $arc\ MN + 150 = 180$
