a pie chart is divided into four sectors in fig. 12.42. Each sector represents a percentage of the whole. The two larger sectors
are equal and each represents x%. What is the angle subtended by one of those larger sectors ?
1 answer:
Answer:
Angle formed by the sector measuring x% will be 126°.
Step-by-step explanation:
Since, sum of all sectors formed in a circle is 100%.
By adding the measures of all the sectors,
x + x + 21 + 9 = 100
2x + 30 = 100
2x = 70
x = 35%
Now we know sum of all the central angles formed at the center of a circle = 360°
Therefore, angle formed by x% = 360° × 35%
=
= 126°
