Question

Find value of cos 80 digiress. ​

Answer 1

Answer:

Hii

Step-by-step explanation:

cos80° = 0.17365

cos 80° = 0.17365

cos 80 degrees = 0.17365

The cos of 80 degrees is 0.17365, the same as cos of 80 degrees in radians.

To obtain 80 degrees in radian multiply 80° by / 180° = 4/9 . Cos 80degrees = cos (4/9 × .

Our results of cos80° have been rounded to five decimal places.

If you want cosine 80° with higher accuracy, then use the calculator below; our tool displays ten decimal places.

To calculate cos 80 degrees insert the angle 80 in the field labelled °, but if you want to calculate cos 80 in radians, then you have to press the swap unit button first.

${\blue{\underline{\underline{\bold{To\:Find:-}}}}}$

• The value of cos 80°

${\green{\underline{\underline{\bold{Solution:-}}}}}$

cos 80° = 0.17365

• The cos of 80° is 0.17365, the same as cos of 80 degrees in radians.
• To obtain 80 degrees in radian multiply 80° by π/ 180° = 4/9×π .
• Cos 80degrees = cos (4/9 × π) .
