Question

find the angle of a quadrilateral if the other angles are 90°,110° and 80°.​

Answer 1

Here we are given three angles of a quadrilateral: 90°,110° and 80°.​

We have to find out the fourth angle

Let us assume the fourth angle to be x

Now, we know that sum of all the angles in a quadrilateral is 360°

Then, x + 90 + 110 + 80 = 360

                       x + 280 = 360

                                x = 360 - 280

                                 x = 80

Hence, the fourth angle of the quadrilateral will be 80°

Answer 2

Answer:

Here we are given three angles of a quadrilateral: 90°,110° and 80°.​

We have to find out the fourth angle

 the fourth angle to be x

Now, we know that sum of all the angles in a quadrilateral is 360°

Then, x + 90 + 110 + 80 = 360

x + 280 = 360

x = 360 - 280

x = 80

the quadrilateral will be 80°
