Answer:
m∠2 = 140°
Step-by-step explanation:
m∠1 = m∠3, since they're vertical angles.
Solve for x:
Plug in 6 for x for either m∠1 or m∠3. Doesn't matter since they're equal.
m∠1 = (2(6) + 28)°
m∠1 = (12 + 28)°
m∠1 = 40°
Now that we know m∠1, we can now solve for m∠2.
m∠1 + m∠2 = 180°
40° + m∠2 = 180°
m∠2 = 140°
Answer:
3.3 ×
Step-by-step explanation:
1. Move the decimal in 33,000 to the left until the number now has a value between one and ten
<em>Original number: </em>33,000.
<em>New number: </em>3.3000 (3.3)
As you can see the decimal has been moved to the left four times.
2. Now we need to plug it into the "scientific notation formula" which looks like this: ×
. 'x' will be the number we just got (3.3) and 'y' will be the number of times we moved the decimal (4).
3.3 ×
I hope I explained this good for you. Let me know if you need more help!
