Question

Q11.The angles of quadrilateral are respectively 100° , 30° , 92º and xº. Find the value of x.
​

Answer 1

Step-by-step explanation:

Sum of all the angles in a quadrilateral =360°

100+30+92+x=360

222+x=360

x=360-222

x=78°

Answer 2

Answer:

Solution;

we know that

Sum of all angles of quadrilateral is 360°

so,

100°+30°+92°+x° = 360°

130°+92°+x° = 360°

222°+x° = 360°

x°= 360°-222°

x°=138°

hence, value of x is 138° .
