Check the picture below.
so we have a rectangle with two circles, the rectangle is a 21x10.5 and the circle's have a radius of 5.25, so let's <u>get the area of the two circles and subtract it from the whole area of the containing rectangle</u>.
Step-by-step explanation:
Let the first angle be x,
second angle= x-45.6°
Now,
x+(x-45.6)°=90°
x+x-45.6°=90°
2x-45.6°=90°
2x=90°+45.6°
2x=135.6
x=135.6/2
x=67.8
Hence,
First angle= x= 67.8°
Second angle= x-45.6°= 67.8°-45.6°= 22.2°
