Question

the angles of a quadrilateral are of a major 120 degree 90 degree 72 degree and X find the value of x​

Answer 1

Answer:

X is 78°

Step-by-step explanation:

The sum of all measures of a quadrilateral is 360°

Therefore 120 + 90 + 72 + X = 360°

X = 360 - 282

Therefore X = 78°

Hope it will help.

Answer 2

It's very simple.

3 angles are given.

Sum of all the angles of quadrilateral =360degree

120+90+72+x=360

x=360-282

After subtraction you will get the value of x.
