Calculate the measure of each exterior angle of a 90 sided regular polygon. Explain.

forsale [732]

90 sides give us 90 angles

sum of all inside angels is (n-2) * 180 deg. where n is number of angels

so one inside angle is
(90-2)*180 deg / 90 = 88* 2 deg = 176 deg.

measure of exterior angle is 360 - 176 = 184 deg.

write the equation of the line that is parallel to the line y=-5/3x-2 and goes throught the point (-3,1)

max2010maxim [7]

Answer:

y = (-5/3)x - 4

Explanation:

The equation of a line with slope m that goes through the point (x1, y1) is:

$y-y_1=m(x-x_1)_{}$

Additionally, two lines are parallel if they have the same slope.

The slope of the line y = (-5/3)x - 2 is (-5/3) because it is the number beside x.

So, the slope of our line is also -5/3.

Therefore, replacing m by -5/3 and (x1, y1) by (-3, 1), we get that the equation of the line is:

$\begin{gathered} y-1=-\frac{5}{3}(x-(-3)) \\ y-1=-\frac{5}{3}(x+3) \end{gathered}$

Finally, solving for y, we get:

$\begin{gathered} y-1=-\frac{5}{3}x-(\frac{5}{3}\cdot3) \\ y-1=-\frac{5}{3}x-5 \\ y=-\frac{5}{3}x-5+1 \\ y=-\frac{5}{3}x-4 \end{gathered}$

So, the answer is:

y = (-5/3)x - 4

What is the surface area of this right circular cone?

docker41 [41]

Answer:

○ B) 624π mm.²

Step-by-step explanation:

$\pi r(r + \sqrt{ {r}^{2} + {h}^{2}}) = S. A. \\ \\ \pi (12)(12 + \sqrt{{12}^{2} + {40}^{2}}) \\ \\ 12\pi(12 + \sqrt{1744}) = 12\pi(12 + 38) = 12\pi(50) = 600\pi \\ \\ 600\pi ≈ 624\pi$
