Solve A+B+C=180 (solve for "B")

Mathematics
1 answer:
erica [24]3 years ago
4 0
Hi the answer is b=180-a-c
We have to subtract a from both sides
a+b+c+-a=180- a
b+c= 180 - a 
Now subtract c from both sides
b+c-c = 180 - a - c
 b=180 - a  - c

There is no solution to the equation sec x = 0
kondaur [170]
The correct answer for the given statement above would be TRUE. It is true that there is no solution to the equation sec x = 0. Why?
<span>Sec(x) is actually 1/cos(x), which can't be absolute zero. Cos(x) ranges between -1 and 1; it would have to be unbounded for sec(x) to reach 0, or in short, it is undefined. Hope this answer helps. </span>
