Question

use the aleks calculator to evaluate each expression. round your answers to the nearest hundredth. tan 62° = sin 51° = cos 18° =

Explanation:

Step1: Calculate $\tan62^{\circ}$

Using a calculator, $\tan62^{\circ}\approx1.8807264654$. Rounding to the nearest hundredth gives $1.88$.

Step2: Calculate $\sin51^{\circ}$

Using a calculator, $\sin51^{\circ}\approx0.7771459615$. Rounding to the nearest hundredth gives $0.78$.

Step3: Calculate $\cos18^{\circ}$

Using a calculator, $\cos18^{\circ}\approx0.9510565163$. Rounding to the nearest hundredth gives $0.95$.

Answer:

$\tan62^{\circ}=1.88$

$\sin51^{\circ}=0.78$

$\cos18^{\circ}=0.95$
