Question

Segment MP is a diameter of circle O.

Circle O is shown. Line segment M P is a diameter. Line segment N O is a radius. Angle N O P is 150 degrees.


Which equation can be used to find mArc M N?

mArc M N – 150 = 360

Answer 1

A

Explanation:

just took exam and got 100%

Answer 2

`arc\ MN + 150 = 180`

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`
