We are given with 90<x<180 degrees and asks for the value of sin(x/2), cos(x/2) and tan(x/2). We just substitute the maximum and minimum angle to the equations. sin (180/2) is equal to 1 and sin (90/2) is equal to
to 1. cos (x/2) is equal to 0≤y≤<span>
. tan (x/2) is equal to 1 to infinity. </span>
Answer:
x = 3
Step-by-step explanation:
First set up the problem like this:
14x-17 = 8x + 1
Now we subtract 14x from each side. This leaves us with:
-17 = 6x+1
Now we need subtract 1 from each side, leaving us with:
-18 = -6x
And now we divide each side by 6x, leaving us with.
3 = x.
And if you insert three into both of the equations, it will result in 25.

Answer:
2m - 9
Step-by-step explanation:
To simplify this, we need to combine like terms. m + m = 2m and -4 - 5 = -9 so the simplified version would be 2m - 9.
