interior angle of n-gon formula: 180 - ( 360 / n)
a 30 sided polygon, so in this case n = 30
so
interior angle = 180 - ( 360 / 30)
interior angle = 180 - 12
interior angle = 168

answer
168 degrees

True, A

Step-by-step explanation:

If you sum two different sides of a traingle it must be greater than the remaining one

We can test that by adding the two smallest sides

1+8=9

9 is obviously greater than 8, so the answer is: true

A. Find y in terms of x if ????y????x=x6y−7 and y(0)=4. y(x)= (8/7x^7+4^8)^(1/8) . B. For what x-interval is the solution define

topjm [15]

Answer:

Step-by-step explanation:

part A)

given

$x=x6y-7$

so y in terms of x would be

$y=(x+7)/x6$

part b)

in order to find intervals of function, we determine the intervals where the function has a positive first derivative . To find intervals, first we find the critical values, or points at which the first derivative of the function is equal to zero. For the given function the intervals would be

put zero in equation

$y=(x+7)/6x$

$y= infinity$

put 1

$y=1.333$

put 2

$y= 0.75$

put 3

$y= 0.555$

hence we can see that the interval is from zero to positive infinity
