B because the 2 is in the hundredths place and then you look behind the 2 which is a 5.
If its five or more you go up and 4 or less you go down, which means that you add one to the 2 which is 3 and you get rid of anything behind the 3 that was the originally.
Let the third angle = x
It would be: 35 + 45 + x = 180
80 + x = 180
x = 180 - 80
x = 100
So, your final answer is 100
Hope this helps!
That would be about 0.5555
Not sure because that’s a lot of numbers
The answer is x=1.
1x-1= 5x+ 3x- 8
1x-1= 8x-8
-1x -1x
-1=7x-8
+8 +8
7=7x
1=x
I hope this helps love! :)
