Given:
Bl parallel to RA.
To find:
The value of x.
Solution:
In triangle ATR and ITB,
[Common angles]
[Corresponding angle]
[AA property of similarity]
We know that the corresponding sides of a similar triangle are proportional. So,



On cross multiplication, we get




Therefore, the correct option is C.
Hey!! I got 90cm for the answer
That would be a right triangle:)
We use real numbers to express almost all measurable quantities, e.g distance, time duration, weight, speed, etc.
