Question

Sec 4A = cosec ( A - 20 ) find value of a

Answer 1

SOLUTION:-

Given:

sec 4A = cosec(A -20°)

To find:

The value of a.

Explanation:

=) cosec (90° -4A) =cosec(A-20°)

We know,sec theta= cosec (90-theta)

=) 90° -4A = A -20°

=) -4A -A = -20° -90°

=) -5A = -110°

=) A= -110/-5

=) A= 22°

Hence,

The value of A is 22°
