Answer:
Step-by-step explanation:
this is an solution
C(3)=Ishann's age
Ishann is 14 years older than Christopher
7*3=21-7=14
So Christopher is 7 years old
The cofunction identities for tangent are:
tan (90° – θ) = cot θ and cot (90° – θ) = tan θ
Step 1: Simplify each side, if needed.
Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.
Step 3: Use Mult./Div. ...
Step 4: Check your answer.
I find this is the quickest and easiest way to approach linear equations.
Example 6: Solve for the variable.
