Step-by-step explanation:
y+43°= 180°( straight angle)
=>y= 180°-43°
=>y=137°
If it simplifies to 3x+15 its correct
Choices 2, 4, and 5 are correct
Answer:
Your answer tho this question is N > 15
Work :
2n>30
<em>Divide both sides by 2.</em>
<em />
2n/2 > 30/2
n>15
Hope this helps
1) cos (150°)=- cos(180°-150°) = - cos(30°) and - cos30° = - √(3) / 2
sin(150°) = sin(180°-150°) =sin30. and sin30° = 1/2
Then : 5/2(cos 150° + i sin 150°) becomes : 5/2{(-√(3) /2 + I (1/2)]
OR 5/4( - √3 + i)
