What can we deduct about the other angles of AXM?

I would also recommend to label angle BAD $\alpha$, and find the other angles of the parallelogram in terms of $\alpha$.

ok i'll do that and let you know

[wanton star]

angle BCD is 180-alpha

angle ABC + ADC =180

@pearl lily what else can i find?

[gritty skiff]

are u sure abt those? perhaps if you label it on the diagram it would be easier

[wanton star]

wait r they the same?

[gritty skiff]

BCD and BAD?

[wanton star]

yes

[untold falcon]

@wanton star notice that ABX and ADM are similar triangles.
Let AB = 1unit and AD = L
Use cosine rule in AXM to find L.
Hence use the fact that DM=MC=1/2 to find the reqd ratio

Not sure why the image is rotated btw. In my phone photos it is not

[wanton star]

ok let me try#

[wanton star]

@untold falcon I got the ratio 1:2

[untold falcon]

What value of L did u get

I got L=sqrt(3)
Ratio= 1/5

[wanton star]

I got root 3 + 1

Ummm

Can you show me ur working pls

[untold falcon]

AM/L = AX/1
AM = L*AX

Using cosine rule
Sqrt(AX² + MX² -2cos(120)*AX*MX) = L*AX

Sub MX = AX, you get
L = sqrt(3)

[wanton star]

Ohh

[untold falcon]

Actually I am usually not allowed to do it.
But since you specifically asked I gave it to u

[wanton star]

WDYM?

[gritty skiff]

did you figure out the error in your working?

[wanton star]

Yes

Now I’m redoing it

**When helping people, please do not dump the full solution. **
Remember that these people are trying to learn concepts, and our goal should be to reinforce them. Giving them a solution will not help.

**Instead, give them hints and guide them toward the correct solution. **
You can ask things like "what part did you get stuck on?" or "what have you tried so far?" or give them a small starting hint. This ensures better learning. For more tips, reach out to Schlaumau (@schlaumau).

Wait

Ahh I see

But I now understand tho

okay nice

Did u get 1/5 as final ans

[wanton star]

Yes
