Answer:
θ=0,π/3,π,5π/3,2π
Step-by-step explanation:
cosθ sinθ-1/2 sinθ=0
sinθ(cos θ-1/2)=0
Either sin θ=0
θ=0,π,2π
or
cosθ-1/2=0
cos θ=1/2=cos π/3,cos(2π-π/3)
θ=π/3,5π/3
Answer:
D) 5
Step-by-step explanation:
a²+b²=c²
12²+b²=13²
144+b²=169
b²=169-144
b²=25
b=√25
b=5
Answer:
2/3
Step-by-step explanation:
All you need to do is plug in the numbers and you'll get the sides.
If function and inverse be

Both will seem to be opposite and similar .
Look at the first one
It is showing like 1 is function and other one is its inverse(Attachment )
Hence 1st one is the answer
