Use the Law of Cosines to determine the indicated side x. (Assume b = 25 and c = 50. Round your answer to one decimal place.)
Rainbow [258]

The law of cosines can be written as:

p^2=a^2+b^2-2\text{abCosP}

Where

p, a, and b are the sides

P is the angle opposite of side p

Now,

x is what we want to find and other two sides given are 25 and 50 (let them be a and b)

Angle opposite to side unknown is 39 degrees, this is Angle P

Substituting, we get:

\begin{gathered} p^2=a^2+b^2-2\text{abCosP} \\ x^2=25^2+50^2-2(25)(50)\text{Cos}39 \\ x^2=3125-2500Cos39 \\ x^2=3125-1942.86 \\ x=\sqrt[]{3125-1942.86} \\ x=34.38 \end{gathered}

As well as this I need help last one tho i think
trasher [3.6K]

Answer:

y=-1/2x+b

Step-by-step explanation:

we can see that the line is going through (0,9) and the closest point is goes through next is (1,7).

so knowing that y=mx+b, we can plug in numbers to this equation.

take on of the points, and find the slope. the slope is -1/2.

so we would plug in one of our points plus the slope into our equation:

7=-1/2(1) +b

now we do the algebra and find that 7 1/2 =b.

so now the equation is y=-1/2x+b.
