Answer:
Okay so this is simple addition, once you know how to do it.
The interior angles of a triangle should always add up to 180 Degrees.
Now that you know this, all you have to do is add the numbers together and see which ones add up to 180 degrees.
A. - 90+42+58=190
B. - 60+60+60=180
C. - 100+48+42=190
D. - 31+75+70=176
Out of these choices the only one that adds up to 180 is B. So your answer would be B.

Step-by-step explanation:
Answer:
x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3
Step-by-step explanation:
Let's solve for x.
3x2+y2=9
Step 1: Add -y^2 to both sides.
3x2+y2+−y2=9+−y2
3x2=−y2+9
Step 2: Divide both sides by 3.
3x^2/3= -y^2+9/3
x^2=-1/3 y^2 +3
x=√-1/3 y^2 +3 or x=-√-1/3 y^2 +3
Hope it helped!
