Answer:
see below for classification
concave: angles less than 180°
regular: sides and angles congruent
sum = 180°(n -2)
Step-by-step explanation:
A) The given shapes are classified and described in the attachment. (A polygon is a plane figure, so a "tripod" and a "dome" are not polygons.)
__
B) A convex polygon has interior angles that measure less than 180°. A concave polygon has one or more reflex angles.
__
C) A regular polygon has all angle measures congruent, and all side lengths congruent.
__
D) The sum of interior angles can be calculated from the formula ...
angle sum = 180° · (n -2) . . . . where n is the number of sides
Answer:
75%
Step-by-step explanation:
9/12 =
9 ÷ 12 =
0.75
Which is 0.75= .75
so 75/100= 75%

Gestation percent of humans is 72.87% and lions is 29.58%. Subtract and humans 43.29% longer.
Answer:
The answer is 12 I believe. This is because we know one of the lengths which is 2. And then we can use the second rectangle to figure out the second side length.
Please forgive me if I am wrong. Thank you and have a nice day!
Step-by-step explanation:
Alright, so if the red jelly beans are x and the yellow jelly beans are y, then
(3/4)y=x. In addition, (4/5)(y-6)=x-3. Plugging 3y/4 into the equation, we get
4y/5-24/5=3y/4-3. Adding 24/5 to both sides and subtracting 3y/4 from both, we get 4y/5-3y/4=24/5-3. Multiplying 4y/5 by 4/4, 3y/4 by 5/5, etc to get a denominator of 20 we get 16y/20-15y/20=96/20-60/20. Multiplying both sides by 20, we get 16y-15y=96-60 and y=36
