The interval on the number line is (-∞, 2) U [3, ∞)
<h3>How to determine the interval?</h3>
From the number line, we have the following inequalities
x < 2 and x ≥ 3
In inequalities, < and > are represented by brackets i.e. ( and )
While ≤ and ≥ are represented by square brackets i.e. [ and ]
So, we have:
x < 2 and x ≥ 3 = 2) and [3
The intervals must be closed and opened with infinity symbols.
So, we have:
x < 2 and x ≥ 3 = (-∞, 2) and [3, ∞)
Replace and with U
x < 2 and x ≥ 3 = (-∞, 2) U [3, ∞)
Hence, the interval on the number line is (-∞, 2) U [3, ∞)

OK 100% of doctors in the mid-1800s found to be correct and all surgeries
I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.
2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)
Next, I add 20 on both sides.
2x + 90 + 3x = 200º
I combine like terms (2x and 3x)
5x + 90 = 200º
I subtract 90 from both sides.
5x = 110º
Divide 110 by 5 to get x.
x = 22
======
For problem two, I label all the angles I know.
49º + 80º + r = 180º
I add 80 and 49.
129º + r = 180º
I subtract 180 and 129 and get 51º, which is your angle for R.
For angle X, you know that angle R plus angle X equals half of a circle, which is 180º
We know from before that 129º is 180º without R, so X is 129º
I hope this helps! Let me know if I'm wrong!
