Step-by-step explanation:
Consider the provided information.
A convex polygon is a polygon with all its interior angles less than 180°.
Regular polygon is a polygon in which all angles are equal and all sides are the same length.
An irregular polygon does not have congruent sides and interior angles.
From the above definitions we can identify the similarities and differences between the interior and exterior angles of both polygons.
Difference:
The interior angles of regular polygon are equal.
Since, the interior angles of a regular polygon are equal, the exterior angles must also be equal to one another.
The interior angle of irregular polygons are not equal, however, each exterior angle may have a different measurement as well.
Similarity:
The sum of interior angles for both polygon are equal. Also the sum of exterior angles for both polygon are equal.
Answer:
82
Step-by-step explanation:
Sides AB and BC are equal, which means angle BAC and BCA have the same measure, as stated in the base angles theorem. Angle BAC is 49 degrees, so angle BCA must also be 49 degrees. The sum of all angles in a triangle is 180 degrees, so angles BAC, BCA, and CBA will add up to 180. Write this in an equation:
BAC+BCA+CBA=180
BAC and BCA both measure 49 degrees:
49+49+CBA=180
Solve for CBA
CBA=180-49-49
CBA=82

Answer:
Ryan practiced 33.66 minutes on Wednesday
Step-by-step explanation:
You do 43.2+37.48 and it equals 80.68
Then you do 114.34-80.68 which equals 33.66
Answer: x = 3
Step-by-step explanation:
-10x - 2y = -30
3x + 2y =9
use elimination method...
-2y and 2y = 0
-10x = - 30
3x = 9
add together...
-7x = -21
solve...
x= 3
It is given in the question that the formula of volume of cone is
Where V is the volume, r is the radius and h is the height.
And we have to find an expression for h.
First we multiply both sides by 3, and on doing that we will get
Now to isolate h, we have to get rid of pi r square by dividing.
Therefore the correct option is B.
