Find the measure of anglexin the figure below:O 95O 55O

jolli1 [7]

Since a triangle equals 180°

We know that x and y angles are the same.

And that 55° + 30° + y = 180°

We just subtract!
sooo
180 - 55 - 33 = 95

So this means y = 95°

And x and y equal the same measurement.
sooo you answer is...

<span>x = 95°

PLEASE HELP ME The cost, C, to produce b baseball bats per day is modeled by the function C

AfilCa [17]

The minimum cost is the y-coordinate of the vertex of the parabola represented by the equation. The x-coordinate is the number of bats.

$C(b)=0.06b^2-7.2b+390 \\ a=0.06 \\ b=-7.2 \\ \\
\hbox{the x-coordinate of the vertex: } \frac{-b}{2a}=\frac{-(-7.2)}{2 \times 0.06}=\frac{7.2}{0.12}=60
$

60 bats should be produced every day to keep costs at a minimum.
