Find the measure of an exterior angle of the regular polygon shown below. a.
1080°

b.
1440°

c.
45°

d.
90°

c. 45

Step-by-step explanation:

The whole exterior angles of a regular polygon is 360. The question is telling to one angle of it. The polygon has 8 sides.

So, 360/8=45.

Hope it helps!

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
