Let's assume
4:5:3 in the form of 4x, 5x, and 3x
least angle is 3x and greatest is 5x and there defference is 45°
5x-3x=45°
2x=45°
x=22.5
Now multiply with value of x
4×22.5=90°
5×22.5=112.5°
3×22.5=67.5
We know that
the sum of angles of quadrilateral is 360°
90°+112.5°+67.5°+x=360° ( angle sum property )
270°+x=360°
x=360°-270°
x=90°
all angles are
90°, 112.5°, 67.5° and 90°
thanks......
