Hi there!

Since you haven't given any numbers, I'll explain what you can do to figure this problem out. First, determine what side you have in relation to the angle (is it adjacent to the angle, it is opposite the angle, is it the hypotenuse?). Then, determine which trigonometry function to use (Sine = opposite/hypotenuse, Cosine = adjacent/hypotenuse, Tangent = opposite/adjacent). Check out the image below if you're confused. Anyway, you can use trigonometry to find the missing side of a triangle when only given angles and a side. All you have to do is plug in the numbers given and solve. (In the image, the O with a line through it represents the angle measurement that will be plugged in there.)

Hope this helps!! :)
If you're still confused or would like help solving a trigonometry problem, feel free to send me a message!

2/3=n/12 solve the proportion

Natali [406]

Answer: $n=8$

Cross-multiply

$2/3=n/12$

$(2)*(12)=n*(3)$

$24=3n$

Flip the equation

$24=3n---->3n=24$

Divide both sides by 3

$3n/3=24/3$

$24/3=8----> n=8$

The temperature, HH, in degrees Celsius, of a cup of coffee placed on the kitchen counter is given by H=f(t)H=f(t), where tt is

hjlf

Answer:

A) f'(t) is negative

B) degc/min

c ) At 20 minutes after the coffee was put on the counter its temperature is 56degc and will decrease by about 1.125 in the next 45 seconds

Step-by-step explanation:

A ) f'(t) is Negative because as the cup of coffee is placed on the counter there is loss of heat from the cup of coffee to the surrounding as t increases hence f'(t) is negative

B ) The units of f'(20) = degc/min

C) At ║f'(20)║ = 1.5 and f'(20) = 56

║f'(20)║ = 1.5 represents the rate of change of temp every 20 minutes = 1.5

therefore after 45 seconds = 3/4 mins. change in temp = (3/4 * 1.5) = 1.125

At 20 minutes after the coffee was put on the counter its temperature is 56degc and will decrease by about 1.125 in the next 45 seconds

What is an equation of the line that passes through the point (-4,-6) and is

Kay [80]

Answer:

y = -1/2c - 8

Step-by-step explanation:

2c - y = 6

2c -6 = y

Slope: 2. Slope of the perpendicular line: -1/2

Point (-4,-6)

y-intercept = -6 - (-1/2)(-4)

b = -6 -2 = -8
