Sector area = central angle / 360 * PI * radius^2
98 PI = (1 / 2) * PI * radius^2
radius^2 = 196
radius = 14
Answer:x=90 °
Step-by-step explanation:
In any circle the exterior angle formed is half of the major arc - minor arc .
Angle formed by tangents or secants = 
The sum of measure of arcs inany circle is 360°.
Minor arc is given as x°.So Major arc = 360-x.
Substituting the given values in the formula :


x=180-x
Adding x both sides we have:
2x=180.
Dividing both sides by 2.x= 90.
