Question

why x=i explain in detail ​

Answer 1

Answer:

see below

Explanation:

the parallel lines form a rectangle and hence each vertex is of 90°

I,e..i + y = 90°...........(1)

but the base line and the normal ( dotted ) at 90°

I,e...x + y = 90° ...........(2)

since (1) = (2)

i + y = x + y

hence.....x = i
