Step-by-step explanation:
Angles a and b are opposite, so they are equal. The same is true for angles O and 3b.
So, the four angles are actually (starting from the left and going clockwise) 3b,b,3b,b
These four angles sum up to 360, so we have

And since a and b were the same, a is also 45 degrees.
It’s larger median one ages the graphs looks bigger
you add both the mixed numbers, which out be 5 2/3 so c.
