Answer:
A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and – according to the International Astronomical Union but not all planetary scientists – has cleared its neighbouring region of planetesimals.

Step-by-step explanation:
In a quadrilateral, the sum of all angles is 360°.
therefore,
A+B+C+D=360°
It's given that 2C=D, A=45°, B=135°
Let angle c be x, so angle d will be 2x.
Put these values into the above equation.
45° + 135° + x° + 2x° = 360°
180° + 3x° = 360°
3x° = 360°-180°
3x° = 180°
x = 60°
Answer:
A= 45°
B= 135°
C= 60°
D= 120°
