Question

what is sin (45°) rounded to the hundredths? make sure the calculator is in degrees. 71 85 90

Explanation:

Step1: Calculate the value of \(\sin(45^{\circ})\)

We know that \(\sin(45^{\circ})=\frac{\sqrt{2}}{2}\approx0.7071\)

Step2: Round to the hundredths place

Looking at the thousandths digit (7), since \(7\geq5\), we round up the hundredths digit. So \(0.7071\approx0.71\)

Answer:

\(0.71\) (corresponding to the first option)
