D. 2.4 m

Answer 1

Hello Shay :-)

Answer 2

Hey wolf ! ^_^

Answer 3

@hartnn is this the same kind of question ?

Answer 4

You must find x and you know the slide length and the angle

Answer 5

I'd say this is the same kind of question

Answer 6

Ok i need more practice with these anyway but before we start can someone label what is sin, con, and tan i promise I won't forget this time lol

Answer 7

Here is my trig chart

Answer 8

You can save that chart to your computer if you want.

Answer 9

lol ok will do

Answer 10

the triangles are situated differently in my chart and the diagram but I think you'll be able to figure it out.

Answer 11

x is opposite ?

Answer 12

we are doing sin for this problem correct ?

Answer 13

4.1 is the hypotenuse

Answer 14

yes - as you can see 'x' is opposite from the 35° angle

Answer 15

yup so sin 35

Answer 16

yes it is for sine which is opposite / hypotenuse

Answer 17

.574 = sin 35

Answer 18

That is correct for sine 35°

Answer 19

ok so now what do i do ?

Answer 20

x/4.1

Answer 21

okay - you know we have to solve for height which is 'x'

Answer 22

and we know the slide length is 4.1

Answer 23

Do you know how 4.1 and 'x' get classified in terms of the 35° angle?

Answer 24

nope

Answer 25

Okay the 'x' relates to the35° angle in what way opp? adjacent? hypotenuse?

Answer 26

opposite

Answer 27

Very good ! and the 4.1 is what part of the triangle?

Answer 28

hypotenuse

Answer 29

Very good - in case you haven't been told, the hypotenuse is:
the longest side of any right triangle and is
always opposite the right triangle

Answer 30

so it's either b or d

Answer 31

Well I like to get the answer first

Answer 32

ok

Answer 33

so sine 35° = opposite / hypotenuse

sine 35° = x / 4.1

Answer 34

yea we know that

Answer 35

So, can you calculate 'x' ?

Answer 36

how am i supposed to do that ?

Answer 37

Okay, that's why I asked.

sine 35° = x / 4.1

Can you multiply both sides by 4.1 ?

Answer 38

2.4 ! so the answer is D

Answer 39

thank you so much !

Answer 40

x = sine 35° * 4.1
x = 2.351
So I'd say 2.4 is close enough!

Answer 41

great!

Answer 42

Okay - you have done well !

Answer 43

thank you lol i tried

Answer 44

Is that all the questions for the moment?
