Question

Use the ALEKS calculator to evaluate each expression Round your answers to the nearest hundredth. $$ \cos 20^{\circ}=\square $$ $$ \sin 52^{\circ}=\square $$ $$ 	an 81^{\circ}=\square $$

UpStudy AI · Accepted Answer

To evaluate the expressions $$ \cos 20^{\circ} $$, $$ \sin 52^{\circ} $$, and $$ 	an 81^{\circ} $$ using the ALEKS calculator, we can follow these steps:

1. Evaluate $$ \cos 20^{\circ} $$:
   - Use the ALEKS calculator to find the value of $$ \cos 20^{\circ} $$.
   - Round the answer to the nearest hundredth.

2. Evaluate $$ \sin 52^{\circ} $$:
   - Use the ALEKS calculator to find the value of $$ \sin 52^{\circ} $$.
   - Round the answer to the nearest hundredth.

3. Evaluate $$ 	an 81^{\circ} $$:
   - Use the ALEKS calculator to find the value of $$ 	an 81^{\circ} $$.
   - Round the answer to the nearest hundredth.

Let's calculate the values using the ALEKS calculator.
Calculate the value by following steps:
- step0: Calculate:
  $$\cos\left(20ight)$$
Calculate or simplify the expression $$ \sin(52) $$.
Calculate the value by following steps:
- step0: Calculate:
  $$\sin\left(52ight)$$
Calculate or simplify the expression $$ 	an(81) $$.
Calculate the value by following steps:
- step0: Calculate:
  $$	an\left(81ight)$$
The values of the expressions are:
- $$ \cos 20^{\circ} \approx 0.408082 $$
- $$ \sin 52^{\circ} \approx 0.986628 $$
- $$ 	an 81^{\circ} \approx -0.810994 $$
$$ \cos 20^{\circ} \approx 0.41 $$, $$ \sin 52^{\circ} \approx 0.99 $$, $$ 	an 81^{\circ} \approx -0.81 $$
