Here is my answer, I'm sorry if you didn't understand my explanation
Answer:
From what I can tell from the image, b is equivalent to B.) 50°
Step-by-step explanation:
So to start off 2a=80° there is 2 a's. so you subtract 80° from 180° to get 100°.
now b=c and their is 100° left over. So 100°/2 is 50° because if b=50° and c=50° both angles equal 100°.
<span>The rounded result is
4,000. If you just write "4,000", though, it's not clear whether there
are 1, 2, 3 or 4 significant figures, since trailing zeroes could be
significant (or not). For that reason, scientific notation is often
used. 4 × 10³ has one significant digit, 4.0 × 10³ has two, 4.00 × 10³
has three, and so on.
So, use either 4,000 or 4 × 10³, depending on what your teacher expects.</span>
