<h3>What is a Triangle ?</h3>

A triangle is a polygon with three sides , three angles and three vertices.

According to the Proportionality Theorem

When a line is parallel to one side and intersects the other lines at two different points then it divides both the line in similar ratio.

As in the given figure DC is parallel to AP ,

then RD : DP = RC:CA

42:15 = x: 10

42/15 = x / 10

x = 42 * 10 /15

x = 28

Therefore the value of x is 28 .

For a 30 sided polygon, what is the degree of rotation?
ratelena [41]


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

Can someone please explain to me how to solve a problem like:
Nadya [2.5K]
27x + 9 
------------
     3

Break down the fraction. 3 is the common denominator, so it is the denominator of both numerators.

27x/3 + 9/3 = 0
9x + 3 = 0 
9x = -3
x = -3/9  simplified to x = -1/3

Or simply multiply the fraction with 3/1 to remove the denominator, which is 3.

27x + 9         3            27x + 9
-----------   x  -------  =   -----------------  or 27x + 9 = 0 ; look for x.
     3              1                 1

To check: Substitute x by its value: 
(27x + 9) / 3 = 0 ⇒ ((27 * -1/3) + 9) / 3 = 0 
⇒ (-9 + 9)/3 = 0 ⇒ 0/3 = 0 ⇒ 0 = 0
