Given the general identity tan X =sin X/cos X , which equation relating the acute angles, A and C, of a right ∆ABC is true?

irakobra [83]

First, note that $m\angle A+m\angle C=90^{\circ}.$ Then

$m\angle A=90^{\circ}-m\angle C \text{ and } m\angle C=90^{\circ}-m\angle A.$

Consider all options:

A.

$\tan A=\dfrac{\sin A}{\sin C}$

By the definition,

$\tan A=\dfrac{BC}{AB},\\ \\\sin A=\dfrac{BC}{AC},\\ \\\sin C=\dfrac{AB}{AC}.$

Now

$\dfrac{\sin A}{\sin C}=\dfrac{\dfrac{BC}{AC}}{\dfrac{AB}{AC}}=\dfrac{BC}{AB}=\tan A.$

Option A is true.

B.

$\cos A=\dfrac{\tan (90^{\circ}-A)}{\sin (90^{\circ}-C)}.$

By the definition,

$\cos A=\dfrac{AB}{AC},\\ \\\tan (90^{\circ}-A)=\dfrac{\sin(90^{\circ}-A)}{\cos(90^{\circ}-A)}=\dfrac{\sin C}{\cos C}=\dfrac{\dfrac{AB}{AC}}{\dfrac{BC}{AC}}=\dfrac{AB}{BC},\\ \\\sin (90^{\circ}-C)=\sin A=\dfrac{BC}{AC}.$

Then

$\dfrac{\tan (90^{\circ}-A)}{\sin (90^{\circ}-C)}=\dfrac{\dfrac{AB}{BC}}{\dfrac{BC}{AC}}=\dfrac{AB\cdot AC}{BC^2}\neq \dfrac{AB}{AC}.$

Option B is false.

3.

$\sin C = \dfrac{\cos A}{\tan C}.$

By the definition,

$\sin C=\dfrac{AB}{AC},\\ \\\cos A=\dfrac{AB}{AC},\\ \\\tan C=\dfrac{AB}{BC}.$

Now

$\dfrac{\cos A}{\tan C}=\dfrac{\dfrac{AB}{AC}}{\dfrac{AB}{BC}}=\dfrac{BC}{AC}\neq \sin C.$

Option C is false.

D.

$\cos A=\tan C.$

By the definition,

$\cos A=\dfrac{AB}{AC},\\ \\\tan C=\dfrac{AB}{BC}.$

As you can see $\cos A\neq \tan C$ and option D is not true.

E.

$\sin C = \dfrac{\cos(90^{\circ}-C)}{\tan A}.$

By the definition,

$\sin C=\dfrac{AB}{AC},\\ \\\cos (90^{\circ}-C)=\cos A=\dfrac{AB}{AC},\\ \\\tan A=\dfrac{BC}{AB}.$

Then

$\dfrac{\cos(90^{\circ}-C)}{\tan A}=\dfrac{\dfrac{AB}{AC}}{\dfrac{BC}{AB}}=\dfrac{AB^2}{AC\cdot BC}\neq \sin C.$

This option is false.

Which measurements are equal to 671 decimeters? Check all that apply.

iren [92.7K]

Answer:

Answer:

Option A , D and E are correct.

67100 millimeters, 6.71 decameters and 6,710 centimeters measurements are equal to 671 decimeters

Step-by-step explanation:

Use conversion:

1 millimeters = 0.01 decimeter

1 kilometer = 10000 decimeter

1 hectometers = 1000 decimeter.

1 decameter = 100 decimeters

1 centimeters = 0.1 decimeter

As per the statement:

We have to find which measurements are equal to 671 decimeters.

A.

67100 millimeters

Using conversion:

1 millimeters = 0.01 decimeter

then;

67100 millimeters = 671 decimeter.

B.

0.671 kilometers

Using conversion:

1 kilometer = 10000 decimeter

then;

0.671 kilometers = 6710 decimeter.

C.

67.1 hectometers

1 hectometers = 1000 decimeter.

then;

67.1 hectometers = 67100 decimeters.

D.

6.71 decameters

1 decameter = 100 decimeters

then;

6.71 decameters = 671 decimeters

E.

6,710 centimeters

1 centimeters = 0.1 decimeter

then;

6710 centimeters = 671 decimeters.

Step-by-step explanation:

then;

0.671 kilometers = 6710 decimeter.

C.

1 hectometers = 1000 decimeter.

then;

67.1 hectometers = 67100 decimeters.

D.

6.71 decameters

1 decameter = 100 decimeters

then;

6.71 decameters = 671 decimeters

E.

6,710 centimeters

1 centimeters = 0.1 decimeter

then;

6710 centimeters = 671 decimeters.
