Answer:
NOT found in obtuse triangles
Step-by-step explanation:
you only talk about hypotenuse, adjacent, and opposite in right triangle
The standard form equation for a circle is
where (h, k) is the center and r is the radius.
The standard form equation for an ellipse is
(center h, k and major and minor axes a and b)
This equation is standard form for neither, but might be general form for one.

Answer: Yes, the point (3,4) is a solution to the system.
===================================================
Proof of this:
Replace x with 3 and y with 4 in the first equation
x+y = 7
3+4 = 7
7 = 7
This confirms the first equation. Repeat for the second equation
x-2y = -5
3-2(4) = -5
3 - 8 = -5
-5 = -5
We get true equations for both when we plug in (x,y) = (3,4). This confirms it is a valid solution to the system of equations. It turns out it's the only solution to this system of equations. Visually, the two lines cross at the single location (3,4).
