Answer:
24 sides
Step-by-step explanation:
Angle at a point = 360°
To find the number of degrees in each interior angle of a regular polygon, we make use of
180(n - 2)/n
There are 8 sides in a regular octagon,
Each interior of a regular octagon= 180(8-2)/8
= 6 * 180/8
= ¾ * 180
= 135°
The interior angle of a regular triangle (equilateral triangle) is 60°
The interior angle of the regular n-gon is given by
360° - 135 - 60°
= 165°
Since the interior angle is 165°
Then
180(n - 2)/n = 165 for the regular n-gon
Solving for n
Multiply both sides by n
180(n - 2) = 165n ------ Open the bracket
180n - 360 = 165n ----- Collect Like Terms
180n - 165n = 360
15n = 360 ----- Divide both sides by 15
n = 360/15
n = 24
Thus, the number of sides of the regular n-gon is 24
Answer:
$6.00
Step-by-step explanation:
2(1.75)+2.50=6
Answer:
61°
Step-by-step explanation:
let the angle on a straight line with 112° be x
112°+x = 180° ( angles on a straight line)
x = 180°- 112°
x = 68°
calculating for k°
68°+ k +51° = 180° (sum of angles Ina triangle equal 180°)
119° +k = 180°
K = 180-119
k = 61°
