i believe its 80 that is my best guess

OpenStudy (anonymous):

How did u get that guess?

OpenStudy (anonymous):

is is just slightly smaller than 90 degrees which is a right angle

jimthompson5910 (jim_thompson5910):

90+y+112+58 = 360 y+260 = 360 y = 360 - 260 y = 100 So the exterior angle x is 180 - y = 180 - 100 = 80 So x = 80

OpenStudy (ash2326):

We have a quadrilateral, In a quadrilateral the sum of the interior angles is 360 degrees. so we have \[y+112+58+90=360\] \[y+260=360\] so \[y=100\] , we need to find x x+y=180 so \[x=80 \]
