No, it didn't help at all. I think to solve questions like this, we need to make extra geometric drawings like creating an equilateral triangle or something else.
Thanks for taking your time

I see how it can. It's a system of linear equations.

P - a + 90 = 180
P + a + A = 180
P + 90 - A = 180

This system has a unique solution, which is

{ a = 30, p = 120 }.

Now use those values to find the unknown.

Thanks, Savio. That was the point I was making.

120 * 3 = 360, which makes sense.
