Question

Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only)

Answer 1

@Michele_Laino @texaschic101 @jacobrocket173 @sleepyjess can anyone help me with this?

Answer 2

Do you know SOH-CAH-TOA?

Answer 3

no i dont understand any of this

Answer 4

have you heard of SOH-CAH-TOA?

Answer 5

or sine, cosine and tangent

Answer 6

i was really sick in school and missed 2 weeks and they sent me this packet with all these questions in it

Answer 7

so i do not know it

Answer 8

Okay, this is going to be interesting...
Sine(x) = opposite/hypotenuse
cosine(x) = adjacent/hypotenuse
tangent(x) = opposite/adjacent

Answer 9

ok that makes sense

Answer 10

Now, what do you think we will use for this question?

Answer 11

sine?

Answer 12

yep :)

Answer 13

ok so how would i use that to find angle X?

Answer 14

We know adjacent and hypotenuse, so sine would be correct

Answer 15

ok cool

Answer 16

sine(x) = 4/5

Answer 17

4/5 = .8

Answer 18

.8?

Answer 19

ok

Answer 20

Ever heard of inverse sine?

Answer 21

or \(sin^{-1}\)

Answer 22

no i havent

Answer 23

Okay, do you have a calculator with sine on it?

Answer 24

yes

Answer 25

Okay, to find sin(x) = .8, you will need to take the inverse sine of .8

Answer 26

about 53.13?

Answer 27

@sleepyjess

Answer 28

hmmm...

Answer 29

because it would be sin^-1(.8) right?

Answer 30

Yeah... give me just a minute

Answer 31

ok

Answer 32

Okay, for arcsin(.8), your calculator is coming up with 53.13?

Answer 33

yes

Answer 34

why is that wrong?

Answer 35

Well then there's something wrong with that calculator... the answer should be .93

Answer 36

ok well ill just put that down... thx for helping me

Answer 37

No problem :)

Answer 38

WAIT

Answer 39

you are right with 53.13!!!! I had the calculator in the wrong mode
