Answer:

The estimated value is 0.01.

Step-by-step explanation:

Given : 17 divided by 1,569.

To find : Use compatible number to find two estimates ?

Solution :

Compatible numbers are pairs of numbers that are easy to add, subtract, multiply, or divide mentally.

Estimation is to approximate a calculation.

Estimating the number 17 is 20.

Estimating the number 1569 is 2000.

Substituting the values,

20 divided by 2000,

$\frac{20}{2000}=\frac{1}{100}=0.01$

Therefore, The estimated value is 0.01.

Answer:

$-2.813$

Step-by-step explanation:

Se simplifica inicialmente la fórmula en términos de las funciones trigonométricas fundamentales (Initially, the formula is simplified in terms of fundamental trigonometric functions):

$(\sec 245^{\circ} + \tan 45^{\circ} )\cdot \cot 37^{\circ} - 2\cos 60^{\circ}$

$\left(\frac{1}{\cos 245^{\circ}}+\frac{\sin 45^{\circ}}{\cos 45^{\circ}} \right)\cdot \left(\frac{\cos 37^{\circ}}{\sin 37^{\circ}} \right) - 2\cdot \cos 60^{\circ}$
