In the diagram below , triangle LMO is isosceles with LO=MO . if angle LL=55 and angle NOM = 28 what is angle N

Respuesta :

Answer:

The measure of angle N is equal to [tex]27\°[/tex]

Step-by-step explanation:

we know that

The triangle LMO is an isosceles triangle

therefore

[tex]LO=MO[/tex]

and

[tex]m<OLM=m<LMO[/tex]

see the attached figure to better understand the problem

we have that

[tex]m<OLM=55\°[/tex]

so

[tex]m<LMO=55\°[/tex]

Remember that

[tex]m<LMO+m<OMN=180\°[/tex] -----> by supplementary angles

Find the measure of angle OMN

[tex]55\°+m<OMN=180\°[/tex]

[tex]m<OMN=180\°-55\°=125\°[/tex]

The sum of the internal angles of a triangle is equal to [tex]180\°[/tex]

In the triangle OMN

[tex]m<MON+m<OMN+m<MNO=180\°[/tex]

we have

[tex]m<OMN=125\°[/tex]

[tex]m<MON=28\°[/tex]

substitute and solve for m< NMO

[tex]28\°+125\°+m<MNO=180\°[/tex]

[tex]m<MNO=180\°-28\°-125\°=27\°[/tex]
