Step-by-step explanation:
First box is EF.
Second box is segment congruence postulate.
Third box is segment additon postulate.
Fourth box is DF. For this one the last sentence basically gives you the answer.
Just so you know for the fourth I guessed on if it's DF lined or DF unlined. I made my educated guess on the fact that the last line doesn't have a line. I hope this helps, and please tell me if I got something wrong, or my explanation wasn't sufficent enough for you.
Answer:
Step-by-step explanation:
To get the other angles you need to do this
110+80+x+x=360
190+2x=360
2x=360-190
2x=170
X=170÷2
X=85
Answer:
Simplify the problems first
Step-by-step explanation:
Before you can convert it to scientific notation, you should simplify it first.
#1 for example:
Use PEMDAS to solve the equation:
So, now we have a super big number. To write it in scientific notation, put a decimal place in the number before the zeroes start. It would be 
since there are 11 places after the decimal.
The answer to this in simpler form is 2/5
