true

Answer 13

These are problems use the pythagorean theorem and a few trig functions
Do you know what the pythagorean theorem is, and what sin, cos, tan are?

yes yes yes and yes

Answer 15

kk, and btw, you don't need to quote me lol

Answer 16

So let's first look at number 5
Because this is a square, all sides are equal
So we find AX using the pythagorean theorem with sides AW and WX
Can you tell me how long AW and WX are?

Answer 17

wouldnt the answer be 1 for how long they are?

Answer 18

...AZ is 1, which means AW is how long?

Answer 19

1 to the square root of 2?

Answer 20

....
WZ=XY, so WZ is 4
But AZ is 1, which means AW is how long

Answer 21

idkkk i rlly dont know

Answer 22

...
When a segment is 4 units long... but one part is 1... so how long is left of it... simple subtraction e.e

Answer 23

oh my im dumb its 3

Answer 24

yee, so it's 3
So now that we have one leg is that is 3 units long, one side that is 4 units long, what is the hypotenuse? (remember that this is a right triangle)

Answer 25

its 5 right becuase its a triple

Answer 26

Yep so number 5 is 5

Answer 27

And then we look at number 6
Use the pythagorean theorem

Answer 28

ok ok

Answer 29

ohhh so with number 6 you just have to write out the probelm with number 8 in the c squared part right?

Answer 30

...what? lol

Answer 31

sry nvm i think i got number 6 but i dont understand 7

Answer 32

Do you know your 45 45 90 triangles?

Answer 33

yea i do

Answer 34

So, 1, 1, sqrt2
If 6sqrt2 was 1, multiply 6sqrt2 with sqrt2, what do you get

Answer 35

wha-

Answer 36

1, 1, sqrt2
6sqrt2, 6 sqrt2, __

Answer 37

So what is \[6(\sqrt2)(\sqrt2)\]

Answer 38

Hint that sqrtx times sqrtx equals x

Answer 39

i got 12

Answer 40

yep

Answer 41

For number 8, do you remember 30, 60, 90 degree triangles?

Answer 42

yea i do

Answer 43

so do you know how to find x adn y

Answer 44

not rlly

Answer 45

You know these sides, and so, put it into the actual triangle, compare and multiply

Answer 46

sqrt3 = 36
\[\sqrt3(12\sqrt3)=36\]

Answer 47

And this is like scaling, so multiply the sides by 12 sqrt3

Answer 48

ohh so the answer for x would be 12sqrt3?

Answer 49

yep
and y would be that times 2

Answer 50

wait wha-

Answer 51

Because y is 2x, as seen in the ^^^ image

Answer 52

okkk then how would i find y?

Answer 53

2 times x

Answer 54

im lost on how to do that sry

Answer 55

\(\color{#0cbb34}{\text{End of Quote}}\)
You know that x is 12 sqrt 3
So y=2x
So what is 2(12sqrt3)?

Answer 56

i got a decimal of 41.56

Answer 57

....Don't do it in decimal... keep it in square root form \[2(12\sqrt3)\]

Answer 58

i did that and got a decimal ;-;

Answer 59

keep it in square root form... what is 12 times 2

Answer 60

Wait, btw, do you know how to multiply square root stuffs?

Answer 61

no i dont

Answer 62

When one is an integer, another a square root, multiply the integers together, in this case, 2 times 12, and then add the sqrt3 behind

Answer 63

i still get a decimal what am i doing wrong?

Answer 64

.... don't use a frickin calculator....
what did i just tell you...

Answer 66

oh my gosh i so fing dumb

Answer 67

I want an answer, not a 'i'm so dumb'

Answer 68

What is 2 times 12

Answer 69

24

Answer 70

so it's 24 sqrt3

Answer 71

oh my ok

Answer 72

ok what abt number 9

Answer 73

So for number 9, it's the 45 45 90 degree triangle thing again
what do youg et

Answer 74

so we have 10 sqrt2 what would i told then?

Answer 75

1, 1, sqrt2
WHat other side is equal to 10 sqrt2

Answer 76

y is

Answer 77

so would y be 10?

Answer 78

.... y would be \[10\sqrt2(\sqrt2)\]

Answer 79

y is 20

Answer 80

yes

Answer 81

ok then what would x be?

Answer 82

.... 1, 1, sqrt2

Answer 83

X is also 10sqrt2 isnt it?

Answer 84

yep

Answer 85

For 10, we have 30 60 90 again, but this one's easier, since we start with the hypotenuse side

Answer 86

okkkkk...

Answer 87

So what do you get for x, remember that it is half the value of the hypotenuse

Answer 88

10.5 is x right

Answer 89

Yes and y is sqrt 3 times x so what is it
Remember, not calculator....
Just... multiply the values

Answer 90

sooo y is 10.5sqrt3?

Answer 91

yep

Answer 92

thxs i might have more

Answer 93

e.e okay lol
