Question

In the triangle below, calculate the value of x.

Answer 1

Sin θ = o/h

Answer 2

Is 4.75 the correct answer

Answer 3

no

Answer 4

multiply 12*sin(57)

Answer 5

These are the answer choices.
a. 10
b.5
c.11.85
d.4.75

Answer 6

sin(theta) = opposite/hypotenuse

therefore hypotenuse*sin(theta) = opposite

Answer 7

I'm sorry but I don't quite understand. I did sin 57. It gave me .8386

Answer 8

please help, I don't understand

Answer 9

Sin θ = a/h
sin(57) = x/12
0.436 = x/12
0.436(12) = x
5.23 = x

Answer 10

The answer would be 5 if I only used one decimal place.

Answer 11

Thanks, Could you explain why you got 12 from?

Answer 12

where

Answer 13

I did sin57 and it gave me 8386

Answer 14

H = 12
h is the hypotenuse

Answer 15

I'm just trying to understand not challenge, I have more to do. I just want to know how to do them. Where did you get 0.436? I did sin 12, and the √ and did not get 0.436. Thanks so much

Answer 16

I didn't type the quesion marks have no clue where that came from

Answer 17

I the place of the question marks I said I also tried the squre root and didn't get the .436

Answer 18

hold up, no it's not 5

Answer 19

make sure your calc is in degree mode

Answer 20

Its in dregree mode. I press sin and put 57 and enter is that how you do it?

Answer 21

@caominhim you're right.

Answer 22

The answer would be 10

Answer 23

So the answer isn't 5?

Answer 24

multiply the hypotenuse by sin(57)

Answer 25

No it's 10.

Answer 26

because sin(theta) = opposite/hypotenuse

Answer 27

I had to put it in degrees.

Answer 28

Its in dregree mode. I press sin and put 57 and enter is that how you do it?

Answer 29

SOHCAHTOA

sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/ adjacent

Answer 30

@freemap yes. that is right.

Answer 31

and yes that gives you the sin value, now multiply that by 12

Answer 32

When I do that Why do I keep getting .8386

Answer 33

because sin(57) = .8386705679

Answer 34

Thanks I just didn't understand where .436 came from. sorry for being annoying.

Answer 35

it's cool, though i don't know where you got .436 from

Answer 36

Thats what lia.may got

Answer 37

oh that's the radian value of sin(57)

Answer 38

oh okay thanks so much for working with me

Answer 39

no problem

Answer 40

Who get the medal?
