Your answer would be option 2. Use the slope formula to see if any sides are perpendicular. This is because a right triangle must have 2 perpendicular sides that form a 90° angle for it to be a right triangle, so finding these would prove it.
I hope this helps!
Answer:
Step-by-step explanation: when h(x) = 10
h(x)= 6-x
h(10)= 6-10
=-4
To get x intercept：
let y=0，x➖12=0，x=12
so x intercept point （12，0）
To get y intercept：
let x=0，3y➖12=0，y=4
so y intercept point （0，4）
I just worked it out and I got 6 3/28
Im sorry if that's wrong
