I am not sure about this... but it’s a.
First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48
Answer:
D
Step-by-step explanation:
y>-3x+1 Negative slope
y<u><</u>x+2 Positive slope
< or > have dotted line
<u><</u> or <u>></u> have a solid line
> or <u>></u> means solutions are above the line
< or <u><</u> means solutions are below the line
The one with negative slope has a dotted line and solutions above it.
The one with positive slope has a solid line and solutions below it.
The answer is C 52 degrees
