Question

In a pie chart,there are four parts.If three angles at the centre are 80°,90°and 70°,find the remaining angle at the centre in degree.

Answer 1

Answer:

(80+90+70)-360

250-369

119

Answer 2

Answer:

Step-by-step explanation:

Let remaining angle be x

Given,

Angles at centre of pie chart 80°,90°and 70°

We know that sum of all angles of a centre of pie chart =360°

So ,80°+90°+70°+ x =360°

240°+ x = 360°

x = 360°- 240°

x = 120°

Hence,the remaining angle of centre of pie chart in degree is 120°
