Answer:
42.21 ft^2
Step-by-step explanation:
The formula: A=1
/2b √ c2﹣b2
c=hypotenuse
b=base
Answer:
D
Step-by-step explanation:
A is (-8,8) so you would divide each 8 by 4 because 8 divided by 1/4 so you will have (-2,2)
B is (-8,4) so divide the by 1/4 which would be (-2,1)
C is (4,-4) so divide that and and you get (1,-1)
We know that
The exterior angle measures of a polygon must add up to 360°,
therefore
360°/72°=5 exterior angles
so
5 exterior angles, would mean 5 interior angles and therefore 5 sides to the polygon
The exterior angle and the interior angle of any polygon are supplementary and must add up to 180°.
exterior angle+interior angle=180°
interior angle=180°-exterior angle
interior angle=180°−72°-------> 108°
Each interior angle is 108°
The sum of the interior angles would be
5*108°=540°
the answer is
540°
Answer:
45 degrees
Step-by-step explanation:
Think of this web as a circle. This circle is divided into 8 equal pieces.
A circle has 360 degrees in it. If we divide 360 by 8, we get 45. This means that each wedge is 45 degrees, which means that in order to rotate the image to look the same, we must rotate it by 45 degrees.
