Answer:
x=12
y=
Step-by-step explanation:
Hey There!
to solve this problem we need to use the 30 - 60 - 90 triangle rule
So you are correct on x because the hypotenuse is 2x
24/2=12
y would equal
as you could see in the image down below
We are given with a circle and we need to find the <em>equation of the circle</em> , but first let's recall that , the equation of a circle with radius<em> 'r'</em> and centre at <em>(h,k) </em>is given by
Now , here as as the circle cuts the +ve x-axis at (9,0) . So , it's radius is 9 units or the 2nd way is to measure the distance from centre of the circle to the point where the circle cuts the graph , as the centre is at Origin , so here <em>(h,k) = (0,0)</em> .Which means that the centre is located at the point whose coordinates are<em> (0,0)</em> which is also known as origin . Now , finding the equation of the circle :-
<em>This is the required equation of Circle</em>
