We are given two relations 
(a)
Relation (R)
![R=[((k-8.3+2.4k),-5),(-\frac{3}{4}k,4)]](https://tex.z-dn.net/?f=R%3D%5B%28%28k-8.3%2B2.4k%29%2C-5%29%2C%28-%5Cfrac%7B3%7D%7B4%7Dk%2C4%29%5D)
We know that 
any relation can not be function when their inputs are same
so, we can set both x-values equal 
and then we can solve for k

(b)
S = {(2−|k+1| , 4), (−6, 7)}
We know that 
any relation can not be function when their inputs are same
so, we can set both x-values equal 
and then we can solve for k 




Since, this is absolute function 
so, we can break it into two parts


we get 




so,

Given that, 
In <u>triangle TPQ, </u>
As it is given that, <u>RS || PQ</u>
So, it means 
⇛∠TRS = ∠TPQ  [ Corresponding angles ]
⇛ ∠TSR = ∠TPQ [ Corresponding angles ]

<u>Now, We know </u>
 Area Ratio Theorem, 
This theorem states that :- The ratio of the area of two similar triangles is equal to the ratio of the squares of corresponding sides.
