40.21/12.5
We would do this because the problem asks for unit rate
And and we need to find out the cost for one square foot
40.21/12.5 = 3.2168
We need to round this ANSWER and round it or else it will be incorrect
The answer would round to 3.22
Therefore, the answer is $3.22 per square foot
Apply the cosine double angle identity to get:
Cos 2PI/3
No that statement is not always true. There is only one solution to this equation.
To find the coterminal angle to the given angle , we need to add or subtract the multiples of 360 degree . Since here we have to find the coterminal of -710 in 0 to 360, it means we have to find a positive coterminal angle . And to find the positive coterminal angle, if we add just 360 degree, we will get -710+360 = -350, but we need a positive coterminal angle, so we add again 360 , that is -350+360 =10.
So the coterminal of -710 in 0 to 360 is 10 degree .
