Answer:
The value of ∅ for the given trigonometrical equation is 60° .
Step-by-step explanation:
Given as :
The Trigonometrical equation
2 cos∅ + 2 = 3
<u>Now, Solving this equation to get the value of ∅</u>
∴ The equation can be written as
2 cos∅ = 3 - 2
or , 2 cos∅ = 1
or , cos∅ = 
∴ ∅ = 
I.e ∅ = 60°
So,The value of ∅ for the given trigonometrical equation = ∅ = 60°
Hence, The value of ∅ for the given trigonometrical equation is 60° . Answer

Answer:
12 years younger.
Step-by-step explanation:
Let Jan's age be J and Karyn's age be K.

Jan's age 8 years ago is 2/5 of Karyn's age 4 yeaRs from now.

=> 
=> 4K = 48 X 3
=> K= 36.
=> J= 24.
So Jan is 12 years younger.
