Find the size of the acute angle formed at A by the intersecting circles. You will first have

to decide what is meant by the phrase the angle formed by the intersecting circles.

My answer is 44.985.

I am not sure I got the point of the problem.

I made an equation for the two tangent lines at (4.3)

Found the coordinates when they meet with the y axis.(made a triangle)

(0, 25/3) (0, 25/7) (4,3)

used the law of cosines and got 44.985.

I wasn't sure what finding the size of the acute angle formed by the intersecting circles meant.
