Answer:
Step-by-step explanation: what triangle?
Answer:
Any collection of lengths (a, b, c) which do not satisfy the triangle inequalities.
Step-by-step explanation:
Any collection (a, b, c) which do not satisfy the triangle inequalities. The inequalities:
a + b > c
b + c > a
a + c > b
You will need to test all of your options on the three inequalities above. If any one of the three fails, the collection won't work.

Step-by-step explanation:
Answer:
Angle 1 is 48°
Step-by-step explanation:
So angle 1 + angle 2 + angle 3 = 180°
Angle 2 = 90°
Angle 3 = 42°
180 - 90 - 42 = 48°
This question is very oddly worded. The domain is the set of x-values, but this is a set of (x,y) ordered pairs.
I'm reading this question as "Here's a function, { (1,5), (2,1), (-1,-7) }. If this is reflected over the x-axis, what's the range?"
Assuming that is the question that is meant to be asked, reflecting a function over the x-axis will just change the signs of the y-values.
(1,5) -> (1,–5)
(2,1) -> (2,–1)
(-1,-7) -> (-1,+7)
I'd pick the third option.
