Answer:
Θ = 50°
Step-by-step explanation:
Using the cofunction identity
cosx = sin(90 - x)
Given
cos40° = sin(90 - 40)° = sin50° ⇒ Θ = 50°

Answer:
Critical points are: 2 , -2 and 3.
Step-by-step explanation:
We have been given the expression:
We will factorize the given expression:
Using
Critical point are those values of an expression when it is equal to zero
Hence, the critical points are: 2,-2 and -3.
Answer: 1/6 = 4/24 1/4 = 6/24
Step-by-step explanation:
Multiply the denominators of the fraction so 6x24 is 24 so the common denominator is 24 now whatever you do to the bottom you do to the top so you do 1x4 which is 4 then that means your first fraction is 4/24 then you do the same to the next fraction so 6x1=6 which means your next fraction will be 6/24 so your 2 fractions right now are 4/24 and 6/24.
