Answer:
The measure of arc MN is 88 degrees
Step-by-step explanation:
The complete question in the attached figure
we know that
The measure of the interior angle is the semi-sum of the arches that comprise it and its opposite
so
[tex]m\angle NQM=\frac{1}{2}(arc\ MN+arc\ LP)[/tex]
we have
[tex]m\angle NQM=103^o[/tex]
substitute
[tex]103^o=\frac{1}{2}(arc\ MN+arc\ LP)[/tex]
[tex]206^o=arc\ MN+arc\ LP[/tex] ----> equation A
Remember that
The measure of arc LP is 30 degrees more than the measure of arc MN
so
[tex]arc\ LP=arc\ MN+30^o[/tex] ----> equation B
substitute equation B in equation A
[tex]206^o=arc\ MN+arc\ MN+30^o[/tex]
[tex]2arc\ MN=206^o-30^o\\2arc\ MN=176^o\\arc\ MN=88^o[/tex]
The measure of MN is 88 degrees
Circle geometry
From the diagram shown, the formula expressed below will be used to determine the measure of MN.
<NMQ = 1/2(arcLP + arcMN)
If the measure of LP is 30 degrees more than the measure of MN, then;
arcLP = 30 + arcMN
<NMQ = 1/2(30 + arcMN + arcMN)
2(103) = 30 + 2arcMN
206 - 30 = 2arcMN
arcMN = 88 degrees
Hence the measure of MN is 88 degrees
