Answer:
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:
144
Step-by-step explanation:
Two over three multiplied by 18 is 12
Answer:
None
Step-by-step explanation:
Assuming you mean sides of a right triangle, we can use the Pythagorean theorem (A^2 + B^2 = C^2)
We have A and B, so we can plug those into the equation.
(16)^2 + B^2 = (14)^2
(16)^2 is 256 and (14)^2 is 196. Plug those in.
256 + B^2 = 196
Get rid of the 256 by subtracting.
B^2 = 196 - 256
B^2 = -60
√B^2 = √-60
You can't take the square root of a negative number, so the solution is not possible. We can confirm because C cannot be bigger than A or B.
