Question

three angles of a quadilateral are 75 90 and 75 then the fourth angle is​

Answer 1

Let the fourth angle be x

then,

75+90+75+x=360

=150+90+x=360

=210+x=360

=x=360-210

x=150

Answer 2

Answer:

Fourth Angle= 120°

Step-by-step explanation:

Let the fourth angle = x

In the given quadrilateral

75° + 90° + 75° + x= 360° (ASP of quadrilateral)

240°+ x= 360°

x= 360-240

x= 120°

Fourth Angle= 120°
