If sin42 degrees = 2/3 then cos48 degrees = what? <br> If tan20.5= 3/8, the tan69.5= what?

Anna11 [10]

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

$10.\\1ft=0.3048m\to1m=\dfrac{10000}{3048}ft\approx3.281ft\\\\therefore\ 14m\approx14\cdot3.28ft1=45.93ft$

$13.\\1mi=1.609km\to1km=\dfrac{1000}{1609}mi\approx0.621mi\\\\therefore\ 0.3km\approx0.3\cdot0.621mi=0.186mi$

$1in=2.54cm\to1cm=\dfrac{100}{254}in\approx0.394in\\\\therefore\ 15cm\approx15\cdot0.394in=5.91in$
