Answer ≈ 4 and a half billion
If we assume your letters range from A to Z and your digits from 0 to 9, you have 26 possibilities per letter and 10 per digit. This gives you 26^4*10^4 which is roughly 4 billion and a half.
C because you have to do 50÷2=25 and 40÷2=20 and 20-25=5

Answer:
∠A = 166°
Step-by-step explanation:
We can imagine the parallel line to the left as a shifted version of the one on the right. As we move it further left along the line the in middle (called a <em>transversal</em>), ∠B will slide closer and closer to ∠A. Eventually, the two will totally coincide, showing that ∠B ≅ ∠A. We call ∠A and ∠B <em>corresponding angles</em>, because they can be made to perfectly overlap in that way.
Since corresponding angles are congruent, their measures must be equal, so in this example, we can say that
, and since
and
,

To solve for <em>x</em>, we can subtract 3x and 40° from both sides:

and divide both sides by 4:

We can now replace <em>x </em>with 18° in our expression for ∠A to find
