please mark me as the brainliest
Step-by-step explanation:
we know that sum of all angles of a quadrilateral is 360°.
Hence angle A=13x
angle B=9x
angle C=5x
angle D=3x
So
A+B+C+D=360°
13x+9x+5x+3x=360°
30x=360°
x=360/30
x=12
Now
angle A=13x
=13×12
=156°
angle B=9x
=9×12
=128°
angle C=5x
=5×12
=60°
angle D=3x
=3×12
=36°
