Question

What is the value of cos 31° - sin59​

Answer 1

Step-by-step explanation:

We know that cos ( 90 ° - x ) = sin x

So

Sin 59° =Sin (90 ° - 31° )

Sin 59° = cos 31 °

Therefore

Sin 59°- Cos 31° = cos 31 ° - cos 31 °

Sin 59°- Cos 31° = 0

And its your answer

Answer 2

Answer:

hii (0) is your ans.

Step-by-step explanation:

we know that..cos(90°-x)=sin x

so

sin 59°=sin(90°-31°)

sin 59°=cos31°

therefore

sin 59°-cos31°= cos 31°-cos 31°

sin 59°-cos31°=0
