Question

find the value of x if a quadrilateral has 55 degree 60 degree 105degree and x in exterior of quadrilateral​

Answer 1

Answer:

x = 140°

Step-by-step explanation:

The sum of exterior angles of quadrilateral is equal to 360°

Therefore, 55 + 60 + 105 + x = 360

220 + x = 360

x = 360 - 220

x = 140
