Question

what will be the measure of the fourth angle of a quadrilateral if the measures of three angles is 1100,800 and 950​

Answer 1

Step-by-step explanation:

"Given,

The three angles are 110°, 50° and 40°

Let the fourth angle be ‘x’

Sum of all angles of a quadrilateral = 360°

110° + 50° + 40° + x = 360°

200° + x = 360°

x = 360° − 200°

x = 160°

Hence, the required fourth angle is 160°."

Answer 2

A N S W E R :

It is given that three angles are equal and measure of fourth angle is 120o.

Let the measure of each of the equal angles be x

We know that, sum of four measure of angles of quadrilateral is 360o.

• ⇒  x+x+x+120o=360o*

• ⇒  3x+120o=360o*

• ⇒  3x=240o*

• ⇒  x=80*

Hence, this is the answer.
