Answer 2

53.9 your equations is cosx= adj/hyp. your adj is 33 and your hyp is 56. divide them and use the inverse cos button on your calculator to get the answer i got (:

Answer 3

\(\Huge\color{blue}{ \sf SOH }\)\(\Huge\color{green}{ \sf CAH }\)\(\Huge\color{red}{ \sf TOA}\)



\(\Huge\color{blue}{ \sf SOH }\) \(\Huge\color{blue}{ \sf Sin =\frac{Opposite }{Hypotenuse} }\)


\(\Huge\color{green}{ \sf CAH }\) \(\Huge\color{green}{ \sf Cos =\frac{Adjacent }{Hypotenuse} }\)


\(\Huge\color{red}{ \sf TOA }\) \(\Huge\color{red}{ \sf Tan =\frac{Opposite }{Adjacent} }\)

Answer 4

ok imma write that in my notes

Answer 5

That's a good way to memorize them

csc would be inverse of sin i.e hypotenuse/opposite

sec would be inverse of cos i.e hypotenuse/adjacent

cot would be inverse of tan i.e adjacent/opposite

(for the INVERSE flip the fraction upside down)

Answer 6

when i divide it it comesout with a bunch of numbers

Answer 7

When you divide what by what ?

Answer 8

look at what i wrote, you gotta use the inverse cos button

Answer 9

when you do that you will still get a bunch of numbers, you round to the nearest 10th

Answer 10

write your answer as a fraction (I mean for Cos(D) )
DON"T PUT A DECIMAL, PLEASE

Answer 11

@ninamarie, he is just dealing with Sohcahtoa right now. He need to find Cos(D) using it, this way he can get a precise value

Answer 12

@Mason_Jones573

Cos= adjacent / hypotenuse

can you tell me what the adjacent and the hypotenuse are ?
