Problem
Solution
For this case we need to remember that the sum of all theinterior angles of any quadrilateral is 360º then we can set up the following equation:
90+90+ x +(x-50)=360
And now we can solve for the value of x
180+2x-50=360
2x= 360-180+50
2x= 230
And we got:
x= 230/2= 115º
Now with the value of x we can find the angles and we got:
x= 115º
x-50º= 115-50= 65º
