Question

find out the angle x ​

Answer 1

Answer:

60°

Step-by-step explanation:

Sum of quadrilateral angles=360°

x+91+120+89=360

x+300=360

x=360-300

x=60°

Answer 2

Here three angles of the quadrilateral are given to be 91°, 89°, and 120°

We have to find the fourth angle

So, we know that the sum of angles of a quadrilateral is 360°

So, x + 91 + 89 + 120 = 360

                    x + 300 = 360

                               x = 360 - 300

                               x = 60°

Hence, the fourth angle will be 60°
