Let's say the angles are "a", "b" and "c"

$\bf \begin{cases}
\stackrel{first}{a}\\
\stackrel{second}{b}=\stackrel{\textit{2 less than 3 times \underline{a}}}{3a-2}\\
\stackrel{third}{c}=\stackrel{\textit{14 more than twice \underline{a}}}{2a+14}
\end{cases}
\\\\\\
\textit{now, the sum of all internal angles in a triangle is }180^o
\\\\\\
a+b+c=\implies a+(3a-2)+(2a+14)=180
\\\\\\
6a+12=180\implies 6a=180-12\implies 6a=168\implies a=\cfrac{168}{6}
\\\\\\
a=28$

so a = 28°, plug that in "b" and "c", to see how much each is.

A sales team estimates that the number of new phones they will sell is a function of the price that they set. They estimate that

Serggg [28]

Answer:

Price x = $120.

Step-by-step explanation:

R = x⋅(2160−9x)

R = 2160x - 9x^2

= -9(x^2 - 240x)

= - 9[ ( x - 120)^2 - 14400)

= -9(x - 120)^2 + 129,600

The maximum value is when x - 120 = 0 That is when x = 120.
