Answer:
z = 15
Step-by-step explanation:
The sum S of the interior angles of a regular polygon is given by the formula
S = (n-2) x 180 where n is the number sides
Here n = 9
So S = (9-2) x 180 = 7 x 180 = 1,260
There are 9 interior angles and each angle is (5z + 65)
So the sum of all 9 interior angles = 9 (5z + 65)
= 45z + 585
Set these equal to each other and solve for z
45z + 585 = 1260
45z = 675
z = 675/45 = 15
Answer:
260
Step-by-step explanation:
28+29(23)
=28+(29)(8)
=28+232
Answer:
There are 96 ways different 4 digit numbers which can be made from these 5 digits.
Step-by-step explanation:
There are 5 different digits. The first one must be
1 3 5 or 7
So you can have 4 for the first one. Now the zero can be put into the mix.
4 * 4 * 3 * 2
96
Answer:
x = 4
Step-by-step explanation:
<em>Perimeter of triangle = sum of all sides</em>
Side 1: 14 - 2x
Side 2: 3x - 1
Side 3: 2x + 1
<em>Perimeter= side 1 + side 2 + side 3</em>
26 = 14 - 2x + 3x - 1 + 2x + 1
26 = 14 - 1 + 1 - 2x + 3x + 2x
26 = 14 + 3x
3x = 12
x = 12/3
x = 4
