Sorry mate hope this helps<3
Hello :
cos(3<span>θ) = -1
</span>cos(3θ) = cos(<span>π)
</span>general solution in : R is
3θ = (2k+1)π k in Z
θ = (2k+1)π/3
if θ in <span> [0 , 2</span>π] the solutions are :
k=0 : x = π/3
k=1 : x = π
k=2 : x = 5π/3
Answer:
True
Hope this helps. Have a great day. :)

.75x-14=-8
Use inverse operations to find x
Add 14 on both sides
.75x=6
divide by .75 on both sides
x=8
Answer: x=-7
Step-by-step explanation:
1) The angles of a triangle are equal to 180
2) Add your angles together and set them equal to 180 like this:
x+59+x+51+84=180
3) Combine like terms:
2x+ 194 =180
4) Subtract 195 from both sides:
2x+ 194 =180
- 194 -194
2x = -14
5) Divide by 2 on both sides
2x= -14
/2 /2
x= -7
