Answer:
4/5
Step-by-step explanation:
sohcahtoa meaning sin is opposite over hypotenuse
Since angles that are vertical to each other are equal to each other, the first thing I did is set 45 equal to 4x+1 which would look something like this: 45=4x+1
Then I solved for x. First, I subtracted 1 from each side to isolate 4x which would get me to 4x=44. Then I divided each side by 4 to isolate x and get me to my answer which would be x=11.
You can take 3x as a common factor from them, then it would be:
3x (5+8a) ......so, it's the equivalent form of that...
I’m pretty sure
8. would be false because BK would be 12 where as DF is 10.8
9. is true
Answer & Step-by-step explanation:
First, we will multiply 5 by 28 to find out the total number of ages in the room.
5 * 28 = 140
Now, we will multiply 6 by 29 to find out the total number of ages in the room after the new person comes in.
6 * 29 = 174
Now, in order for us to find the age of the new person, then we will subtract 140 from 174.
174 - 140 = 34
So, the person that entered the room is 34 years old.
