Question

the value of degree of tan 855​

Answer 1

Answer:

-1

Explanation:

For any degree over 360, subtract intervals of 360 off until it is less, for example

855−360= 495 − 360=135

So you are looking for

tan (135) this is halfway between 90 and 180 degrees. This means it behaves like 45 degrees, but with cos being the negative of cos(45) , since

tan(45)is 1

tan (135) is -1

Answer 2

Answer:-1

Step-by-step explanation:For any degree over 360, subtract intervals of 360 off until it is less, for example

855

−

360

=

495

−

360

=

135

So you are looking for  

tan

(

135

)

this is halfway between 90 and 180 degrees. This means it behaves like 45 degrees, but with cos being the negative of  

cos

(

45

)

, since  

tan

(

45

)

is 1  

tan

(

135

)

is -1
