1.	Find the value of x.(a) 3/140(b) 150/7(c) 140/3(d) 7/150The question was asked in quiz.Origin of the question is Sum of Measures of the Exterior Angles of a Polygon in section Quadrilaterals of Mathematics – Class 8
Answer» The correct OPTION is (c) 140/3 Easiest explanation: Here we are GIVEN a TRIANGLE with all it’s internal angles marked in terms of x. Now we will use the PROPERTY of triangle. Therefore (x+20)°+(x+30)°+(x-10)°=180° Therefore x+20+x+30+x-10=180 Therefore 3x=140 Therefore x=140/3.
