Answer:
the constant of proportionality is 6.32
Answer:
<em>The correct option is: 82°</em>
Step-by-step explanation:
In the given diagram, two chords
and
are intersecting.
According to the <u>Angle of intersecting chord theorem</u>, "<em>If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle</em>."
That means here......

So, the measure of arc
is 82°
15 is the answer . What you do is unsimplify 2/5 which equals .4 . Then divide 6 and .4 which is 15
