a. hexagon, convex
b. pentagon, concave
c. heptagon, convex
d. decagon, concave
Step-by-step explanation:
Count the sides. Refer to your memory or a list of polygon names for the appropriate name.
If any internal angle measures more than 180°, the polygon is concave. Otherwise, it is convex.
ANSWER
EXPLANATION
Coterminal angles are angles in standard position that have the same terminal side.
To find an angle in standard position that is coterminal with
We add or subtract multiples of
The first addition gives,
We add the second multiple to get,
Since this is the maximum value among the options, we end the addition here.
Let us now subtract the first multiple to get,
We end the subtraction here because this is the least value among the options.
Therefore the angles that are coterminal with
are
Answer:
The opposite of integer 4 units away from -6 is 10.
Step-by-step explanation:
We know that the opposite of the opposite of a number, say 2, is the number itself.
That is:
Opposite of 2 is -2.
Then the opposite of -2 is:
- (-2) = 2
Now consider a number line.
The number that is 4 units away from -6 is -10.
- 4 units away implies moving backwards 4 units from -6.
So, the number is -10.
The opposite of -10 will be:
- (-10) = 10
Thus, the opposite of integer 4 units away from -6 is 10.
Answer:
x=8
Step-by-step explanation:
x=5+3
= 8
Unit rate because unit is referring to one so for example for every unit, there are 6 apples. The unit in the case would be a box
