Question

Find 'x' in the following...

please.. ​

Answer 1

Answer:

120 °

Step-by-step explanation:

Sum of angles of a quadrilateral is 360° and three angles are given i:e 90°, 90°and 60°

So by Angle sum property

=>90 + 90 + 60 + x = 360°

=>180 + 60 + x = 360°

=>240 + x = 360 °

=>x = 360 - 240

=>x = 120

So the value of 'x'would be 120 °
