and what is 1/(3/2)?
16,108
233
[]
volunteer
Maybe 2/3 ?
16,108
234
[]
student
yes
16,108
235
[]
volunteer
and that is the answer !!!
16,108

I thnk I can show another way if you want
16,108

I suspect you can find more examples on the Web
16,108

student
ok
16,108

Do u have a textbook for ur course?
16,108
251
[]

yes i believe so
16,108
252

volunteer
OK do u know hwo the author is?
16,108

student
I just need help with this problem its asking me to find AD
16,133
4
[]
volunteer
Sure! Do you have an idea where to start?
16,133
5
[]
student
nope
16,133
6
[]
volunteer
That's okay! Let's start by looking at the tick marks on the sides of triangle ABC
16,133
7
[]
volunteer
Do you know what the tick marks mean?
16,133
8
[]
student
share the same length?
16,133
9
[]
volunteer
Yes! Very good :) So triangle ABC is an equilateral triangle, a triangle where all sides are the same length.
16,133
10
[]
volunteer
What does that say about the angles of triangle ABC?
16,133
11
[]
student
shares the same angle as the other triangle
16,133
12
[]
volunteer
Are you saying each angle in the triangle shares the same value as the other angles?
16,133
13
[]
student
yea
16,133
14
[]
volunteer
Yes! That's correct :) What is the value of each angle in triangle ABC then?
16,133
15
[]
student
the value?
16,133
16
[]
volunteer
yeah, how many degrees is it?
16,133
17
[]
student
65?
16,133
18
[]
volunteer
Close! If we add together all the angles in any triangle, we 180 degrees. Here we have 3 angles that are all equal in degree that add up 180 degrees. How can we solve for the degree of an angle in triangle ABC, x, if we know 3x = 180?
16,133

16,133

[]
volunteer
very good!
16,133
21
[]
volunteer
So we know each angle in triangle ABC is 60 degrees. Can you find then the degree of each angle in triangle ABD?
16,133
22
[]
student
60deg , 90 deg and 45?
16,133
23
[]
student
angle A would be 30 right
16,133
24
[]
volunteer
Yes that's correct!
16,133
25
[]
volunteer
So...
16,133
26
[]
volunteer
Triangle ABD is a 30-60-90 triangle because the degrees of its angles are 30, 60, and 90 degrees.
16,133
27
[]
student
gotcha
16,133
28
[]
volunteer
Have you learned the ratios of a 30-60-90 triangles hypotenuse to its side lengths?
16,133
29
[]
student
I'm not sure
16,133
30
[]
volunteer
We can review those ratios! They'll be important for solving this problem
16,133
31
[]
volunteer
Any questions so far?
16,133
32
[]
student
nope
16,133
33
[]
volunteer
Do you feel like you have an idea how to apply the ratios to your problem?
16,133
34
[]
student
sorta
16,133
35
[]
volunteer
Do you want to give it a shot?
16,133
36
[]
student
yea
16,133
37
[]
volunteer
Awesome! :)
16,133
38
[]
student
so would I just plug in sqrt(3) / 2 h
16,133
39
[]
volunteer
Yeah! Except h here is 19 m
16,133
40
[]
student
ok
16,133
41
[]
student
so sqrt(3) /2 (19 ) m?
16,133
42
[]
volunteer
Yes!
16,133
43
[]
student
ok
16,133
44
[]
volunteer
So the ratios of the hypotenuse to side lengths of a 30-60-90 triangle are good to memorize
16,133
45
[]
student
16.45 meters
16,133
46
[]
volunteer
Same for 45-45-90 triangles. I'll put those ratios up on the board as well
16,133
47
[]
student
ok
16,133
48
[]
volunteer
Is there anything else you'd like help with? :)
16,133
49
[]
student
is the answer I got correct
16,133
50
[]
volunteer
Yes!
16,133
51
[]
student
ok thank u for ur help today
16,133
52
[]
volunteer
No problem! :)
16,133
53
[]
student
wait
16,133
54
[]
student
should I round my answer
16,133
55
[]
student
even tho it doesn't ask
16,133
56
[]
volunteer
I would ask your teacher how many decimal places they want you to round too. There's not a standard, so it depends what they're looking for. Good question :)
16,133

student
ok byyyyeee
