Respuesta :
You do 120+48+92=280
All angles in a quadrilateral add up to 360, so 360-280=80
The answer is 80

Answer:
Measure of fourth angle of quadrilateral is:
100
Step-by-step explanation:
We know that the sum of angles in a quadrilateral is 360°
Three of the angles of a quadrilateral are 120 48 and 92
we have to find the sum of the fourth angle of the quadrilateral
Let measure of fourth angle be x
120+48+92+x= 360
i.e. 260+x = 360
Subtracting both sides by 260, we get
x= 100
Hence, Measure of fourth angle of quadrilateral is:
100
