Answer: 108
Step-by-step explanation:
So, the quadrilateral's full degree is 360.
EX: 90+90+90+90= 360.
A=?
B=?
C=74 degrees
D=88 degrees
That means A+B+C+D= 360 degrees.
To simply, A+B+74+88= 360 degrees.
Then, A+B+162= 360 degrees.
To find out what is A & B, we can do
360-162.
360-162=198.
And that is the A & B's amount.
A & B= 198 degrees.
198+162=360.
Since it's 90 degrees, we do 198-90.
198-90 is 108.
X=108 degrees.
The answer should be 108.
I hope that helps :D
I hope you understand my horrible explain!
