Answer:
cos (12+10) = cos (22)
Step-by-step explanation:
Cos 12* cos 10* - sin 12* sin 10*
Appling the trig identity: cos (a + b) = cos a.cos b - sin a.sin b
inputing the values of a and b
cos (12 + 10) = cos 12cos 10 - sin 12sin 10 = cos (22)
Rounding 5.6192 -
First you look at the hundredth place: If the number is 5 and higher round it up, if its 4 and lower round down. In this case 1 is in the hundredth place which means you round down. So 5.6192 rounded is 5.6
Answer: 5.6 or 5.60
