Answer:

c = 14

Step-by-step explanation:

For this triangle we have to

a=18.2\\B=62\°\\C=48\°

We want to find the length of b

We know that the sum of the internal angles of a triangle is 180 °

then

A + 62 +48=180\\\\A=180-62-48\\\\A=70\°

Now we use the sine theorem to find the length of c:

\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}

Therefore:

\frac{sin(A)}{a}=\frac{sin(C)}{c}\\\\c=\frac{sin(C)}{\frac{sin(A)}{a}}\\\\c=a*\frac{sin(C)}{sin(A)}\\\\c=(18.2)\frac{sin(48)}{sin(70)}\\\\c=14

Nina operates a dog walking service. She charges a flat fee of $15 plus $5 per hour. Which equation represents this linear relat
densk [106]

Equation for linear relationship is y=mx+b, where m is slope (rate of change), and b is y-intercept. Y-intercept is where you start of at. Like if I had 20 dollars and started earning 5 dollars each day, my y-intercept would be 20 dollars.

Your rate of change is $5 dollars PER HOUR, and y-intercept is $15 dollars. this is because it is a flat fee. She could walkyour dog for 5 minutes but she still charges 15 dollars.

y=5x+15
