Question 1022338
Given the information with the image below:
circle is: {{{ x^2 + y^2=625}}}

and

the equation for AC is: {{{ y=3/4 x}}}
*** AC is a straight line, so it's not {{{ y=3/4 x}}}
It's {{{y = (3/4)x = 3x/4}}}
------------
Sub for y in {{{ x^2 + y^2=625}}}
{{{ x^2 + (3x/4)^2 = 625}}}
{{{ x^2 + 9x^2/16 = 625}}}
{{{25x^2/16 = 625}}}
{{{x^2 = 400}}}
--> x = 20, y = 15 --> C(20,15)
----
x = -20, y = -15 --> A(-20,-15)
