\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}\\\\
-----------------------------\\\\
\textit{so, let's find the missing side}
\\\\\\
c=\sqrt{2.7^2+3.4^2-2(2.7)(3.4)cos(40^o)}
\\\\\\
c=\sqrt{4.78542402433556327368}\implies c\approx 2.187561204706182220

or we can round it, to say c = 2.19, so  hmm that's the missing side
now, we use Heron's Formula, which uses all 3 sides only

\bf \textit{Heron's Area Formula}\\\\
A=\sqrt{s(s-a)(s-b)(s-c)}\qquad 
\begin{cases}
a=2.7\\
b=3.4\\
c\approx 2.19\\\\
s=\cfrac{a+b+c}{2}
\end{cases}

and that'd be the area of it

What is the value of x in the equation -6/7= -×/84?
pantera1 [17]
-6/7 = -x/84

84/7 = 12

12(-6) = -72

x = -72

So, -6/7 = -72/84 because -72/84 simplifies to -6/7

Mr. Douglas drove 2,482 miles. He spent 42.5 hours in the car driving. What was his average speed for the trip?
riadik2000 [5.3K]

I think you just divide the number of miles by the number of hours he spent driving.

2,482/42.5= 58.4

58mph
