In circle O, what is m∠MAJ?

we know that
The measure of the interior angle is the half-sum of the arcs comprising it and its opposite.
so
Find the measure of the angle LAM
m∠LAM is equal to
[tex]\frac{1}{2}*[arc\ KJ+arc\ LM]= \frac{1}{2}*[170+80]\\\\=125\ degrees[/tex]
Find the measure of the angle MAJ
we know that
m∠LAM+m∠MAJ=[tex]180[/tex]° ------> by supplementary angles
m∠MAJ=[tex](180-125)[/tex]
m∠MAJ=[tex]55[/tex]°
therefore
the answer is
The measure of the angle MAJ is [tex]55\ degrees[/tex]
Applying the angles of intersecting chord theorem, m∠MAJ = 55°.
According to the angles of intersecting chord theorem, when two chords intersect, then half of the sum of the measures of the two intercepted arcs equals the measure of the angle formed.
Given:
Thus:
m∠MAL = 1/2(170 + 80)
m∠MAL = 125°
Therefore:
m∠MAJ =180 - m∠MAL
m∠MAJ = 180 - 125
m∠MAJ = 55°
Therefore, applying the angles of intersecting chord theorem, m∠MAJ = 55°.
