Answer:
Step-by-step explanation:
AB is a midsegment.
<u>Property of the midsegment is midsegment is half the length of the parallel side of the triangle:</u>
<u>And</u>
Answer:
The length of the legs is 8.64cm and 14.64cm respectively
Step-by-step explanation:
I've added an attachment to aid my explanation.
At different intervals, I'll be making reference to it.
Given



From the attachment, we have:

Since, M is the Midpoint

Substitute 17 for AB


Also, from the attachment


Substitute 8.5 for y


--------- (1)
Also, from the attachment

Substitute 8.5 for z


----------- (2)
Subtract (2) from (1)


Make x the subject

Apply Pythagoras Theorem:
We have that:

The above can be replaced with
(see attachment)

Substitute 6 + w for x




Reorder

Solve using quadratic equation:

Where







Split:
or 
or 
or 
But length can't be negative
So:

Recall that: 


<em>Hence, the length of the legs is 8.64cm and 14.64cm respectively</em>
Negative rate of change just means that the graph is falling. On this one, that's everywhere after x=0.5. The only choice that's completely in that section is the last one.
