Answer:

f(x)=-3x+14

Step-by-step explanation:

y +1=-3(x–5)

y +1=-3x+15

y= -3x+15-1

f(x) = -3x + 14

Find the height of the triangle.

wel

Answer:

Step-by-step explanation:

BCD is a right triangle. The Pythagorean Theorem applies; a^2 + b^2 = c^2, with c being the hypotenuse. a^2 + 9 = 25, so a^2 = 16, so a = 4

What is the sum of the exterior angles, one at each vertex, of a polygon with 20 sides?A.20B.360C.180D. We need more information

ale4655 [162]

The measure of an exterior angle in a polygon with n sides is given by:

$a_n=\frac{360}{n}$

So, for n = 20, we have the measure of the exterior angles of the polygon with 20 sides:

$\begin{gathered} a_{20}=\frac{360}{20} \\ a_{20}=18\degree \end{gathered}$

Now, to find the sum of all exterior angles, let's multiply the exterior angles by the number of sides of the polygon:

$\begin{gathered} S_{20}=a_{20}\cdot n \\ S_{20}=18\cdot20 \\ S_{20}=360\degree \end{gathered}$

Therefore the sum is equal to 360°, correct option: B.

(The sum of exterior angles of a polygon with n sides is always equal to 360°)
