Question

two angles of a quadrilateral are 72 degree and 122 degree if the other two angles are equal find the equal angles of the quadrilateral

Answer 1

Answer:

let the  angle be x

72+122+x+x=360  then 194 +2x=360

2x=360-194   then 2x=166  then x=166/2= 83

then 2 angle are equal and they are 83and 83

Step-by-step explanation:

Answer 2

sum of all angles of quadrilateral= 360degree
72 degree + 122 degree + x degree +x degree=360 degree
194 degree + 2x degree =360 degree
2x degree = 360 degree-194 degree
2x degree = 166 degree
x degree=166 degree/2
x degree = 83 degree


so the two equal angles of quadrilateral is 83 degree
