Question

pls solve the Q.3 urgently

Answer 1

Answer: ans is x= 3..actually..Not very sure about it

Answer 2

Answer:

1

Step-by-step explanation:

sin^-1 (x/5) + cosec^-1(5/4) = π/2

sin^-1 (x/5) + sin^-1 (4/5) = π/2

sin^-1 (x/5 + 4/5) = π/2

sin^-1[(4+x)/5] = π/2

(4+x)/5 = sinπ/2

(4+x)/5 = 1

x = 1
