Question

if three angles of a quadrilateral are 45 degree,120 degree,100 degree ,then the fourth angle will be

Answer 1

Answer:

95degree

Step-by-step explanation:

120+45+100+x=360. (angle sum property)

265+x=360

x=360-265

x=95degrees

Answer 2

Answer:

let the fourth angle be x .

Then ,

120 + 100 + 45 + x = 360 ( Sum of all angles of quadrilateral is 360 )

265 + x = 360

x = 360 - 265

x = 95

Hence , the fourth angle of the quadrilateral will be 360 .
