Sylvia is correct because a right triangle needs to have 1 right angle and 2 acute angles, it cannot have more than 1 right angle.
Answer:
approximately 42.05
Step-by-step explanation:
We know that the distance formula is 
, so if we use (3,8) as point 2 and (21, -30) as point 1 (note that these are interchangeable), we know that
x₂=3
y₂=8
x₁=21
y₁=-30
Then, we can plug it into the formula to get 
Your answer is 6
6 * 3 = 18
If you are just simplifying it it would be 6x because it's 5x plus one more x but if you are trying to find x then I have no idea
I got 1.5, but I could be wrong.
