Calculating intersection of arc and line

[SpencerW]

Hi. I need to calculate the circled y point, where the inner arc meets the inner vertical line.

I normally try and find a triangle for which I know 3 attributes amd can thus solve but can't for the life of my see one with more than 2 and am stuck where to start given my otherwise limited maths skills!

I'd appreciate any pointers on how to approach the problem.

Thanks

Create the circle equation for a circle with center (60, 120) and radius R = 106.

Plug in the given value of x.

Solve for the desired value of y.

If you get stuck, please reply showing your work so far. Thank you!

Thank you for the response. I feel a bit daft for not realising the equation for a circle is a triangle! I think I was looking at the wrong points in trying to find one.
