Trigonometry as taught is mostly about memorizing two lousy triangles, namely half a square and half an equilateral triangle. This one is half an equilateral triangle.

The respective opposite sides of the 30/60/90 triangle are in ratio 1:\sqrt{3}:2

A sine of √3/2 is an opposite of √3 and a hypotenuse of 2, so opposite and hypotenuse of the 60 degree angle. (It's the mama bear, in the middle, just right.)

\sin 60^\circ = \dfrac{\sqrt{3}}{2}

In the end you just have memorize the two tired triangles of trig.

Answer:

The inequality is 0.6x < 12.5

The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

Step-by-step explanation:

14 gallons-1.5 gallons=12.5 gallons    

we know that  

If the remaining fuel is greater than  1.5 gallons Diego's father can drive the car without the warning light coming on    

so  

Let  

x ----> the number of days

0.6x < 12.5 inequality that represent the situation  

Solve for x

x < 12.5/0.6

x < 20.8 days

The maximum number of days that Diego's father can drive the car without the warning light coming on is 20 days

67a(t+z)=45z+67 solve for z.<br> I need help. Please?
xeze [42]
67a(t+z)=45z+67
Distribute the 67a to inside the parenthesis.
67at + 67az = 45z + 67
Subtract 67 to the other side.
67at + 67az - 67 = 45z
Divide everything by 45.
1.49at + 1.49az - 1.49 = z

Hope that helped! :)

Answer: The only difference between the six functions depends on the sides we use.

Step-by-step explanation:

The primary trigonometry ratio are

Sine  (sin)

Cosine  (cos)

Tangent  (tan)

The reciprocal ratio are derived from the three primary functions. Because they can easily be derived, calculators and spreadsheets do not usually have them. These are:

Secant  (sec)

Cosecant  (csc)

Cotangent  (cot)
