Yes, good job,
a triange has 180 degrees in total so subtract 80 and 60 and you are left with 40

Yes, the third angle is 40 degrees. Every triangle has three angles, which together total 180 degrees.
Therefore, you have 80+60 which equals 140. 180-140=40

I would say B) 40 degrees because 80 - 60 = 40, that's easy to find the any angle.
Example, 1st angle of 30 degrees and 2nd angle of 50 degrees so what is degrees of third angle. The answer is 20 degrees because 50-30 = 20.

Triangles are 180 degrees.
80 + 60 = 140.
180-140=40.
The third angle must be 40 degrees.

B) 40 degrees
All have to add up to 180 degrees

2+2(6+9) constantly multiply the 1st in the previous including 2+12+18 upload 32 then artwork on the backside a million/2 8^2 + 5 artwork on 8^2 sixty 4+5 upload sixty 9 so which you wind up with... 32/sixty 9 positioned into lowest words divide the two element by 8 answer is... 4/9
