<span>First of all in order to find the exact value by using a half angle identity we will do
cos(5π divided by 12)
=cos (5π divided by 6) divided by 2
= ± Under root[(1+cos (5π divided by 6) divided by 2]
Now we will consider + sign because 5π divided by 12 is in quadrant. where cos>0
so the solution is [(1- Under root 3 divided by 2) divided by 2]
We will ignore the negative sign
I hope it helped.</span>
Answer:
Step-by-step explanation:
45h + 75 = 210
45h = 135
h = 3 hours
Answer:
see below
Step-by-step explanation:
for 1)
angle y = 180 - 110 = 70 degrees
angle z = angle y = 70 degrees
angle x = 89 degrees
for 2)
angle 1 = 180 - 85 = 95 degrees
angle 2= 180 - 95 - 85 degrees
angle 3 = 180-95 = 85 degrees
for 3)
m angle 3 = 25 degrees, same as m angle 1
Answer:
you do 8/2 which is 4, so that is ur radius
you do 3.14*4*4=50.24
there is ur answer!
