4. (10 points) From the given triangle: a) Find the value of side a. if the other sides are 13 for the hypotenuse and 5
b) Find the following trigonometric values:
sinθ =
cosθ =
tanθ =
cscθ =
secθ =
cotθ =

sinθ =  y/r        sinθ =

cosθ =  x/r       cosθ =

tanθ =  y/x       tanθ =  

cscθ =  r/y       cscθ =

secθ =  r/x       secθ =  

cotθ = x/y       cotθ =

explanation:

r =

r = 10

x = 8

y = -6

r =

r = 5

x = 4

y = 3

p> q if you calculate p is100 q is 79

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
