Answer:
It is -22.3
Step-by-step explanation:
Since it is subtraction, the answer must be smaller than -13.4. -4.5 is bigger than -13.4 so it is incorrect. The answer is -22.3
The interior angles of a 9-agon add up to (9 -2)*180° = 1260°. The sum of the given angles is
.. 1139° +x° = 1260°
.. x = 1260 -1139 = 121
The missing angle measure is 121°.
_____
The supplement of each interior angle is its corresponding exterior angle. The sum of exterior angles of any convex polygon is always 360°. Another way to approach this problem is to add the exterior angles.
X = 15
Since 6 is 75% of 8
X should be 75% of 20 therefore being 15
It will take 120 fifty pound bags.
90* counterclockwise
Since the star move to the left once.
270* clockwise
If you got to the right, it turns 3 times. 90 * 3 = 270
Its turning left so clockwise.
