Question

If sin (36+x )=cos(16+x) then find x

Answer 1

Answer:

19

Step-by-step explanation:

Here sin (36 + x ) = cos (16 + x)

We know sin Ф = cos(90 - Ф)

∴ cos [ 90 - ( 36 + x)] = cos (16 + x)

Comparing both sides

90 - (36 + x) = 16 + x

90 - 36 - x = 16 + x

54 - 16 = 2x

2x = 38

x = 19
