Answer:

108º

Step-by-step explanation:

to find the sum of interior angles: ( n − 2 ) × 180 = x

x = 540º

n = # of interior angles

first, solve for n

(n - 2) • 180 = 540                        distribute to 180 to (n - 2)

180n - 360 = 540                         add 360 to both sides

180n = 900                                  divide both sides by 180

n = 5

to find measure of each angle:

540 ÷ 5 = 108º

Answer:

n=3.5 a=1.41 units  a'=4.95 units b3 units b'10.5 units c2.24 units c'=7.83 units

Step-by-step explanation:

This answer assumes that n = 3.5. The ratio of each side length on  to the corresponding side length on  is equal to 3.5. For example, a′ = 3.5a. The ratio is equal to the scale factor, n.

Characteristic equation:

r^2+4r-5=(r+5)(r-1)=0\implies r=-5,r=1

\implies y_c=C_1e^{-5x}+C_2e^x

Given that y(0)=0 and y\left(\dfrac\pi2\right)=1, you have

\begin{cases}0=C_1+C_2\\1=C_1e^{-5\pi/2}+C_2e^{\pi/2}\end{cases}\implies C_1=\dfrac{e^{5\pi/2}}{1-e^{3\pi}},C_2=-\dfrac{e^{5\pi/2}}{1-e^{3\pi}}

so that the particular solution is

y=\dfrac{e^{5\pi/2}}{1-e^{3\pi}}(e^{-5x}-e^x)
