Answer 2

Answer:

0

Step-by-step explanation:

We need to find the value of

Cos76° - Sin14°

as we know that Cosα = Sin(90 - α)

putting α = 76°

=> Cos 76° = Sin ( 90° - 76°)

=> Cos76° = Sin14°

Hence Cos76° - Sin14°

= Sin14° - Sin14°

= 0

or using Sinα = Cos(90 - α)

putting α = 14°

=> Sin14° = Cos(90 - 14°)

=> Sin14° = Cos 76°

Cos76° - Sin14°

= Cos76°  - Cos 76°

= 0
