Question

find the value of x
​

Answer 1

Answer:

We know that in this rectangle all sides = 360 degree

Step-by-step explanation:

now 100+a +b+x= 360 degree

100 +90+90( a and b were right angles already given) + x= 360 degree.

100+180+x= 360 degree

280+x = 360 degree

therefore x= 360 - 280=80 degree

so x = 80 degree
