Question

hey physics experts ❗

let this question be solved together ☺..

detail answer required!!!​

Answer 1

From your question one initially tends to believe that a, b and c are line segments.

It is given that a + b = c and simultaneously a = c. This implies that b = 0.

This means that b is a “line segment” of zero length. As this is not possible, we infer that b is just a point.

Your question is, “what is the angle between a and b?”

On can talk of an angle between two lines but not between a line and a point.

The information that c is perpendicular to a is superfluous.
