Answer:

Step-by-step explanation:
<u>Given expression is:</u>
= 10 + 3(12 ÷ (3x))
Put x = 2 nd use PEDMAS [Parenthesis Exponents Division Multiplication Addition Subtraction "in that order"]
= 10 + 3(12 ÷ (3)(2))
Solve Parenthesis
= 10 + 3(12 ÷ 6)
Now, Divide
= 10 + 3(2)
Now, Multiply
= 10 + 6
Now, Add
= 16

secx=1/cosx
1. To solve this problem you must apply the following proccedure:
2. You have to verify if secx sinx=tanx, so, you have:
3. You know that secx=1/cosx, and tanx=sinx/cosx, therefore:
(secx)(sinx)
(1/cosx)(sinx)
sinx/cosx
tanx
