Question

There are three sectors in a pie - diagram Of the angles of two sectors are 80° and 140°then the angle of the third sector is​

Answer 1

Answer:

Step-by-step explanation:

Complete angle = 360 degree

Therefore, 3rd sector = 360- (80+120)

=360-200=160 degree

Answer 2

The angle of the third sector=140 degrees

Step-by-step explanation:

In pie- diagram

Angle of one sector=$80^{\circ}$

Angle of second sector=$140^{\circ}$

Let x be the angle of third sector

We know that

Sum of angles of all sector=Complete angle

Sum of angles of all sectors=$360^{\circ}$

Substitute the values then we get

$80+140+x=360$

$220+x=360$

$x=360-220$

$x=140$

Hence, the angle of the third sector=140 degrees
