Question

find the value of x:​

Answer 1

sum of angles of a quadrilateral is equal to 360 degree

therefore angle all the angles are

first angle given 90 degree

second angle there is a straight line and one part is 70 degree then the remaining part will be 180 - 70 degrees which will is equal to 110 degree

third angle is equals to X

fourth angle there is a straight line and one part is given as hundred degree then 180 - hundred is equals to 80 degree

therefore edition of all the angles is 90 degree + X + 80 + 110 +90=360°

X=360-(80+90+110)

x=360-280

x=80°

therefore the value of x is 80 degree
