Answer:
3a. The polygon has 15 sides, so it is a pentadecagon or a 15-gon.
3b. Each interior angle measures 156°.
3c. The measure of an exterior angles is 24°
Step-by-step explanation:
3a
(n - 2)180 = 2340
n - 2 = 13
n = 15
The polygon has 15 sides, so it is a pentadecagon or a 15-gon.
3b
2340/15 = 156
Each interior angle measures 156°.
3c
There are 2 ways to calculate the measure of an exterior angle.
Method 1:
Each exterior angle is supplementary to its adjacent interior angle.
156 + x = 180
x = 24
Method 2:
The sum of the measures of the exterior angles of a polygon, 1 per vertex, is 360, no matter the number of sides.
360°/15 = 24°
The measure of an exterior angles is 24°
Answer:
a) 9.35550
5 digits: 9.35550
4 digits: 9.3555
3 digits: 9.356
2 digits: 9.36
b) 7.57530
5 digits: 7.57530
4 digits: 7.5753
3 digits: 7.575
2 digits: 7.56
Step-by-step explanation:
for rounding if the last digit is less than 5 then the last digit remains same, but if the last digit is 5 or greater than 5 then the last digit is increased by 1 or rounded off to next digit.
We can use a system of equations in order to solve for both of the numbers. Let's start off by assigning variables to each number. The bigger number can be 'x', and the smaller number can be 'y'.
We can make two equations from the given:
x = 18 + y
("One number is 18 more than another number")
x + y = 36
("The sum of the numbers is 36")
If you look at the first equation, the variable 'x' already has a value (18 + y). We can input its value into the second equation in order to solve for y:
x + y = 36
(18 + y) + y = 36
18 + 2y = 36
2y = 18
y = 9
Input the value of 'y' into the first equation:
x = 18 + y
x = 18 + 9
x = 27
<u>One number is 27 and the other number number is 9.</u>
