Question

Three of the angles of a quadrilateral are 120 48 and 92 what is the size of the 4th angle

Answer 1

You do 120+48+92=280 All angles in a quadrilateral add up to 360, so 360-280=80 The answer is 80 HAVE FUN DOING MATHS!

Answer 2

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
