We know that a quadrilateral has 4 angles in total. The sum of the angles is 360 degree. Therefore, by the condition, 20+4x-5+5x-2+145=360. or,9x+158=360 or,9x=360-158 or,9x=202. or,x=202/9=22 4/9 . Ans:The value of x is 22 4/9. (as a mixed fraction).

Given angles are 20 degrees , (4x-5) degrees , (5x-2) degrees and 145 degrees We know that sum of all angles of a quadrilateral is equal to 360 degrees ⇒20+4x-5+5x-2+145 = 360 ⇒9x+158 = 360 ⇒9x = 360-158 ⇒9x = 202 ⇒x = 202/9 ⇒x = 22 4/9 .
