Answer:
1. D
2. B
3. A
4. C
Step-by-step explanation:
1. Vertical angles are a pair of opposite angles formed by the intersection of lines. Choice D has two lines intersecting, and two opposite angles formed by it.
2. Adjacent angles are two angles that have a common vertex and common side but do not overlap. Choice B is two angles with a common vertex and common side, and they don't overlap.
3. Supplementary angles are angles that add up to 180 degrees/make a straight angle. Choice A has two angles that add up to 180 degrees, and the two angles combined make a straight angle/line.
4. Two angles are called complementary angles if they add up to 90 degrees and form a right angle. Choice C has two angles that form a right triangle, meaning it adds up to 90 degrees.
Answer:
in order to find the area, we should break up the figure. you can see that in the image we have a quarter of a circle and a square. here are the areas for each of these shapes
square:
circle:
but since we only have a quarter of this circle we need to divide the area by 4 so the formula becomes
now we can plug in our numbers
we are given 6 m for our radius or length of square
the square will be (6)^2 = 36 m^2
now onto our circle
π(6)^2/4 = 28.26 m^2
now add these two shapes together to find the total area = 64.26 m^2
Answer:
8.55 inches tall
Step-by-step explanation:
equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.
Now plug in 4.6 for t you get:
h = -0.75t + 12
h = -0.75(4.6) + 12
h = -3.45 +12
h = 8.55 inches tall
Answer:
C. 24 12/20
Step-by-step explanation:
4 3/4 × 6 4/5
24 3/4 × 4/5
24 12/20
1 + i? I think. Because they are both negative because you aren't actually subtracting just adding a negative
