We have question
<span> /*8 (multiply both sides by 8)</span>
/*6 (multiply both sides by 6)
/-30 both sides
8W=-66-30
8W=-96
W=-12

Answer:
Step-by-step explanation:
Use a cofunction identity on the right hand side or left hand side...
So .
We have the equation:
Make the above replacement:
Since cotangent has period 180 degrees, we can also write this as:
So solving the following will give us a set of solutions for :
Add on both sides:
Subtract 10 on both sides:
Divide both sides by 2:
Symmetric property:
