In the following question, a Statement of Assertion (A) is given followed by a corresponding Reason (R) just below it. Read the Statements carefully and mark the correct answer-
Assertion(A): If b = 50, c = 63 and ∠B = 54º, then no such triangle exists.
Reason(R): Since , b > c sin B ⇒ no triangle is formed.
