Answer 3

@whpalmer4

Answer 4

Using the Pythagorean theorem, \(a^2+b^2=c^2\), find the length of the hypotenuse.

Answer 5

can you please write the steps out...I wont forget to give u a medal

Answer 6

@agent0smith are you going to help please

Answer 7

We went through this yesterday. What are the two known sides of the triangle?

Answer 8

4 and 3

Answer 9

and we dont know the hypotenuse it dosent give it

Answer 10

Okay. One of them is \(a\), and the other is \(b\). Figure out the value of \(c\) so that \[a^2+b^2=c^2\]

Answer 11

25=c2

Answer 12

Okay, you're getting warm. What is the value of \(c\) that makes that true?

Answer 13

5?

Answer 14

?

Answer 15

Yes, \(c = 5\). Good! Now we know the length of the hypotenuse.

Answer 16

That means our triangle now looks like this:

Answer 17

Problem asks "Find the value of sin x° and cos y°. "

Do you remember what SOH CAH TOA means?

Answer 18

alittle bit

Answer 19

SOH = Sin of an angle is Opposite side / Hypotenuse
CAH = Cos of an angle is Adjacent side / Hypotenuse
TOA = Tan of an angle is Opposite side / Adjacent side

First one to do is \(\sin x\). What is the length of the opposite side from angle \(x\)?

Answer 20

3

Answer 21

Good. What is the length of the hypotenuse?

Answer 22

5

Answer 23

Excellent. Now you know everything you need to know to tell me the value of \(\sin x\). \[\sin x = \]

Answer 24

3/5

Answer 25

0.6

Answer 26

There we go!

Answer 27

Now, for all the marbles, can you figure out the value of \(\cos y\)?

Answer 28

I give medals for correct answers :-)

Answer 29

You need to identify the adjacent side to angle \(y\), then compute adjacent/hypotenuse.

Answer 30

3/5 again

Answer 31

Yes! Wasn't so hard, was it?

Answer 32

It was easy wow thanks can you just help me with one last one please

Answer 33

Sure, post it and tag me...
