If;
A = Adjacent
O = Opposite
H = Hypotenuse
Then,
Sin Ф = O/H
Cos Ф = A/H
Therefore,
(Sin Ф)/Cos Ф) = (O/H)/(A/H) = (O/H)*(H/A) = O/A
Now,
tan Ф = O/A ----
Therefore, it is true that
tan Ф = SinФ/CosФ
A is located, as you look A is past -2 almost hitting -3 making the mark 2.8 so the answer is A
Solution:
we are given that
If G is the midpoint of FH, it mean that

we are also given that

So we can write

So 
I think its (<span><span>x^2)</span>+<span>5x</span></span>+<span>49</span>
The answer is 136 because 7 x 18 is 126 then + 10 is 136
