Answer:
n = 13
Step-by-step explanation:
The sum of the measures of the interior angles of an n-sided polygon is
(n - 2)180
Set (n - 2)180 equal to 1980 and solve for n.
(n - 2)180 = 1980
Divide both sides by 180.
n - 2 = 11
Add 2 to both sides.
n = 13
Answer:
The graph that best represents the given equation in the attached figure
Step-by-step explanation:
we have
![y=2^x+1](https://tex.z-dn.net/?f=y%3D2%5Ex%2B1)
Find the y-intercept
Remember that the y-intercept is the value of y when the value of x is equal to zero
For x=0
substitute
![y=2^0+1=2](https://tex.z-dn.net/?f=y%3D2%5E0%2B1%3D2)
The y-intercept is the point (0,2)
The given function is increasing, because the y-value increases as the x-value increases. The function tends to go up as it goes along
therefore
The graph that best represents the given equation in the attached figure
Triangle area calculation formula 1. The known triangle bottom is a and the height is h, then S=ah/2. 2. If the two sides of the triangle are known to be a, b, and the angle of the two sides is C, then the product of the triangle with two sides multiplied by the sinusoidal value of the angle, that is, S=(absinC)/2. 3. Let the triangle trilaterals be a, b, c, and the radius of the inner tangent circle is r, then the triangle area S=(a+b+c)r/2.
Answer:
1/9
Step-by-step explanation:
You take 1/6 times 4/6 which equals 1/9.
Hope that helped! :)
Answer:
L=8 & w=5
Step-by-step explanation:
L-3=w
perimeter=2(length+width)
26=2(L+L-3)
26=2(2L-3)
13=2L-3
16=2L
L=8 so w=8-3
w=5
