Question

use the aleks calculator to evaluate each expression. round your answers to the nearest hundredth. tan75° = cos58° = sin15° =

Explanation:

Step1: Calculate $\tan75^\circ$

Using a calculator in degree mode, $\tan75^\circ \approx 3.732$
Round to nearest hundredth: $\tan75^\circ \approx 3.73$

Step2: Calculate $\cos58^\circ$

Using a calculator in degree mode, $\cos58^\circ \approx 0.5299$
Round to nearest hundredth: $\cos58^\circ \approx 0.53$

Step3: Calculate $\sin15^\circ$

Using a calculator in degree mode, $\sin15^\circ \approx 0.2588$
Round to nearest hundredth: $\sin15^\circ \approx 0.26$

Answer:

$\tan75^\circ = 3.73$
$\cos58^\circ = 0.53$
$\sin15^\circ = 0.26$
