25% is 1/4 so you do 8 times 1/4 and that's 2.
-2*4=-8
-8 is the correct answer
R= 18
d=r(2)
36=r(2)
36/2=r(2)/2
18=r
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°
