please give the explanation
No scam ​

Answer 1

Step-by-step explanation:

sum of the angles in a quadrilateral =360

so

x-10+x+25+x-35+x-20=360

4x-40=360

4x=360+40=400

x=400/4=100

Answer 2

Answer:

x = 100

Step-by-step explanation:

Since this is a 4-sided closed shape, it is a quadrilateral.

The angles in a quadrilateral should sum up to 360 degrees.

(x-10) + (x-20) + (x+25) + (x-35) = 360

x-10+x-20+x+25+x-35 = 360

4x - 40 = 360

4x = 360 + 40 = 400

x  = 400/4 = 100
