Answer:

the length of third side is 16.

Step-by-step explanation:

We can use Law of Cosine to find the third side of the triangle.

Law of Cosine is given by

a^2=b^2+c^2-2bc\cosA

Substituting the known values, we get

a^2=12^2+19^2-2\cdot12\cdot19\cos56

On simplifying, we get

a^2=505-456\cos56\\\\a^2=250.008\\\\a=15.81

When rounded to nearest whole number, the length of third side is 16.

Kendra gets a paycheck of $300 after 5 days of work. At this rate, how much does she get paid for working 24 days?
11Alexandr11 [23.1K]

Answer:

$1440

Step-by-step explanation:

First, find the unit rate by dividing 300 by 5, which equals 60. So, Kendra earns $60 in one day. Then, multiply 60 by 24, which equals 1440. So, Kendra makes $1440 in 24 days. Hope this helped!

In which cases would the boundary line be represented by a dashed line when graphing an inequality?
Anarel [89]
Boundary lines are dotted whenever the sign is strictly greater than or less than.

The only reason a line is not dashed would be that it would be equal to. A quick way to remember this would be that the extra line provided to make it equal would fill in the blanks. Hope this tip helps you, helped me ace many tests!
