Question

given the triangle below, find sec X, tan X, and cos Z in fraction form (pic included)

Answer 1

Hello :)

Answer 2

are you there?

Answer 3

yeah

Answer 4

lol do you know how to do this one?

Answer 5

yep

Answer 6

are you familiar with SOH CAH TOA?

Answer 7

sort of

Answer 8

ok, lets find cos Z first

Answer 9

how?

Answer 10

cos z= adj/hyp

Answer 11

so 15 / 25? or?

Answer 12

thats right

Answer 13

.6

Answer 14

they said in fraction form so 15/25 or 3/5 work

Answer 15

oh.. okay so cos z = 3/5 .. whats next? :/

Answer 16

find tanx

Answer 17

how?

Answer 18

Find the missing side

Answer 19

use pythagorean

Answer 20

Do you know how to do that

Answer 21

so a^2 + b ^ = c^?

Answer 22

thats right

Answer 23

25 = c
625 - 225 = 400
20

Answer 24

good job
now find tanx

Answer 25

25 / 20 or 20/ 25?

Answer 26

opposite / adjacent

Answer 27

15 / 20
3/ 4

Answer 28

well done

Answer 29

what about secx

Answer 30

now sec x

Answer 31

whats the formula?

Answer 32

secx = 1/cosx

Answer 33

20 / 15?

Answer 34

how do i do that?

Answer 35

is cos opposite/adjacent
adjacent/hypotenuse
or opposite/hypotenuse

Answer 36

opposite / hypotenuse

Answer 37

nope

Answer 38

Try to remember SOH CAH TOA

Answer 39

SOH: sin = opposite/hypotenuse

Answer 40

CAH: cos = adjacent/hypotenuse

Answer 41

TOA: tan = opposite/adjacent

Answer 42

so 15 / 25?

Answer 43

nope

Answer 44

remember sec = 1/cos

Answer 45

the hypotenuse is 25?

Answer 46

cos is adjacent/hypotenuse

Answer 47

take the reciprocal to get hypotenuse/adjacent

Answer 48

secx=hypotenuse/adjacent

Answer 49

Don't forget, we're looking at x

Answer 50

so 20 /25 or 25 / 20?

Answer 51

hyotenuse/adjacent

Answer 52

25 / 20

Answer 53

5/4, good job

Answer 54

awesome! thanks :)
