Cosx=5/8
i) find the exact value of the other five trigonometric functions associated with the angle

ii) use your gdc to find the degree measure of theta and the other acute angle

All the trigonometric ratios are mentioned and the value of x = 51.32°

Step-by-step explanation:

we are given the value of cosx =

We have to find all the other 5 trigonometric values.

sinx = =

       =

tanx = =

cosecx =

secx =

cotx = =

These are the values of the trigonometric functions.

cosx =

x =

x = 51.32°

The other acute angle = 90 - 51.32 = 38.68°

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
