QUESTION⤵️

what is the value of cos 70degree .

ANSWER⤵️

Cos 70° = 0.34202

The cos of 70 degrees is 0.34202, the same as cos of 70 degrees in radians. To obtain 70 degrees in radian multiply 70° by π / 180° = 7/18π. Cos 70degrees = cos (7/18 × π).

EXTRA INFORMATION

The identities of cosine 70° are as follows:

cos70°

= sin (90°+70°) = sin 160°

= sin (90°-70°) = sin 20°

-cos70°

= cos (180°+70°) = cos 250°

= cos (180°-70°) = cos 110°

$\purple{Note \: that \: cos70° \: is \: periodic: \: cos \: (70° + n × 360°) = \: cos 70 \: degrees, \: n \: belong \: to \: Z.}</p><p></p><p></p><p>[tex] \implies\pink{BE \: \: BRÃÎÑLY}$
