Step-by-step explanation:
2pi is less than 6.4. 2 pi is equal to about 6.28. that's the only choice with the correct answera
Answer:
C
Step-by-step explanation:
There’s nothing hard with this
You need to know special right triangles
This is a 30,60, 90 triangle
We automatically know becuase theres. Right angle (90) and a 60 degree angle
now the formula is the smallest side is (n) {I’m using N becuase theres already an X) or in this case, 6
The hypotenuse, the one directly above the 2nd biggest side, or the diagnoal side is 2n or (12). Now we know what X is in this situation which is 12. So that narrows it to 2 answers
Now the side on the bottom of the hypotenuse, the second biggest side is used in the formula N. So we know what N is in the beginning, 6 so we just plug that in and well get C. Attached is a photo on q 30, 60, 90 special right triangle
2x + 8 = 10
2x + 8 -8=10-8
2x = 2
2x/2 = 2/2
x = 1 ( 2 x 1 + 8 =10)
You treat is like an equation but keep the inequality sign
So
2y<-18+8
2y<-10
y<-5
