angle bisectors meet at a point and that point is the centre of an inscribed circle. I think that could help.

We aren't here to do your homework for you.
But... I'll give you some pointers.

The centre of C1 happens to also be the centre of the triangle.

Finding the height of the triangle would be beneficial towards finding the coordinates of the centre of C1, as well as the radius. To find the height, you can use a^2 + b^2 = c^2.
4. Well I used the bisectors and found where they intercept and I now have an equation so I'm probably gonna work my way through with the smaller circles using where the lines intercept
