Answer:

The answer is A.

Step-by-step explanation:

Given that the total interior angles in a quadrilateral is 360°. So in order to find the 4th angle, you have to subtract the remaining angles from 360° :

[tex]θ + 120 + 100 + 75 = 360[/tex]

[tex]θ + 295 = 360[/tex]

[tex]θ = 360 - 295[/tex]

[tex]θ = 65[/tex]
