Question

three angle of quardrilater are 60,110and 75 .find the fourth angle

Answer 1

Sum of all Angles of a quadrilateral is 360 degrees
so,60+110+75+x = 360 d
245+x = 360d
x = 360-245
x = 115 degrees

Answer 2

we  know  that  sum  of  angles  of  a  quadrilateral  is  360.then  let  the  fourth  angle  be  x.
therefore,60+110+75+x = 360
245+x = 360
x = 360-245
x = 115.
therefore,fourth  angle  of  a  quadrilateral  is  115.
