Big ifs, question writers. These are of course approximations.

The "co" in cosine comes from complementary angles. It means since

$42^\circ + 48 ^\circ = 90^\circ$

$\sin 42^\circ = \cos 48^\circ$

Answer: cos 48° = 2/3

Similarly,

$20.5^\circ +69.5^\circ = 90^\circ$

$\tan 69.5^\circ = \cot 20.5^\circ = \dfrac{1}{\tan 20.5^\circ} = \dfrac 8 3$

Answer: tan 69.5° = 8/3

5.21.

To find this, give both numbers decimal points before setting up a subtraction equation as so:

15.00 - 9.79

Then proceed to solve to get the final answer of 5.21.

Hope this helps!

The only solution to this equation is 8/3, therefore the answer is C.
