Answer:
the correct one is c, which is the second option
Step-by-step explanation:
The exterior angle of a polygon is 360.
And for a rectangle, they have equal exterior angles.
So a rectangle has 4 sides
So each exterior angle=360/4
Then each is 90°
Then the correct c which has 90°
Answer:
D. right; scalene
Step-by-step explanation:
As you can see in the diagram you have a 90, 50, and 40 degrees angles. Because one of the angles is equal to 90 degrees (a right angle) this triangle can be classified as a right triangle.
No congruent sides are shown.... That means it's a scalene.
Answer:
A

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
