The half angle formula is:
sin x/2 = +/- √ (( 1-cos x ) / 2 )
5π/12 = 5π/6 : 2
sin 5π/12 = +/- √(( 1 - cos ( 5π/6)) / 2 )
cos 5π/6 = cos 150° = -√3/2
≈ 0.966 ( this is sin 5π/12 )
Answer:
albinia modern alpinia is not a magnet is called the albanian language
< o and < m are congruent because opposite angles are congruent
3t - 15 = 2t + 10
3t - 2t = 10 + 15
t = 25
3t - 15 = 3(25) - 15 = 75 - 15 = 60...< m = 60
< m and < o are consecutive angles and they are supplementary....so they add up to 180
< m + < o = 180
60 + < o = 180
< o = 180 - 60
< o = 120
3s = 120
s = 120/3
s = 40
Answer:
m = 200N
Step-by-step explanation:
3000N = m(15m/s²) Divide both sides by 15 to find the mass
200N = m
Answer:
<em>y = - 3x + 2 </em>
Step-by-step explanation:
y = - 3x + 5
Slopes of parallel lines are equal
( - 1, 5)
y - 5 = - 3(x + 1)
<em>y = - 3x + 2</em>
