Question

Find the value of cos36degree upon sin54degree

Answer 1

Answer:

1

Step-by-step explanation:

cos 36 degrees/sin 54

cos(90-54) /sin 54

sin54/sin54= 1

Answer 2

Answer:

1

Step-by-step explanation:

$cos( \frac{\pi}{2} - x) = sin(x)$

cos(36)/sin(36) =cos(90-54)/sin(54)

= sin(54)/sin(54)=1
