For this case we have that by definition, the sum of the internal angles of a triangle is 180 degrees. So, we have:
We add similar terms:
Answer:
Option D
Answer: y=-3-1/2x
i hope this helps and good luck
Well I got 17.5
You would start with 6x1=6
Then you would add 7: 6+7=13
Next you would multiply 13 by (1/2): 13(1/2)=6.5
Finally you would add 11 to 6.5: 6.5+11= 17.5
Answer:
X = 30
Step-by-step explanation:
1) Y + X = 88
2) 58 + X = 88
-58 -58
------------------------
X = 30
I’m not sure but since no one else commented I would think it’s D, I think you take the first number like 6 for a and subtract the first number for b like 3
