Answer:
Least to greatest #1 - 0.3, 0.35, 0.5, 0.53, 3.5
Least to greatest #2 - 9.6, 9.67, 9.7, 9.76, 19.6
<em>Least meaning the lowest/smallest number.</em>
<em>Greatest meaning the highest/ biggest number.</em>
Cos 157.5º=-cos (180º-157.5º)=-cos 22.5=-cos(45/2)
cos Ф/2=⁺₋√((1+cosФ)/2).
In this case 157.5º is in the second quadrant, therefore we use the following equation:
cos Ф/2=-√((1+cosФ)/2). (we will have a negative number)
cos 157.5º=-cos (45/2)=-√((1+cos 45º)/2)
=-√((1+√2/2)/2)
=-√((2+√2)/4)
=-√(2+√2) / 2 (≈-0.92387...)
Answer: cos 157.5º= -√(2+√2) / 2
