Line of symmetry is the line which cuts the figure into two same halves
or we can say that which passes through the figure such that it makes one half the mirror image of the other half
So we can see from the figure that y=-2 is the line which cuts the figure in to equal halves
So
y=-2
Third option
1 1/4*30=37.5 because, first to make this easier to work with I like to turn the fraction into a decimal like so, 1/4=.25 because 1/4=.25 so 1/4=.25, so now we have 1.25*30=? What this is pretty much saying is that 30+(25% of 30)=? Which to solve this we just need to find how much 25% is of 30 which is .25*30=7.5 because 7.5*4=30 making it true that this is 25% of 30. Now what we have to do is take 30+7.5 (because we have a 1 infront of the 25% we add this instead of subtract it, if we had no whole number infront of the 30 and where solving this that way we would have to subtract instead of add) which adds up to be are end answer of 37.5.
Hope that this helps and makes sense, Enjoy!=)
No.4- This is not a triangle since one side should be less than the sum of the 2 other sides. In this case 8=3+5, hence it's equal & not smaller
N0.5- This is an isosceles triangle & there are an infinity of triangles with the mentioned degrees. (these are called similar triangle)
No6- This is a unique triangle
No.7- If the plane is parallel to the bases, then the slicing is a cercle.
But if the plane (Parallelogram) is tilt, then the slicing is an ellipse
Answer:
The answer to this question is: 12.96 ft ≈ 13 ft
Step-by-step explanation:
Data
Area 168 ft²
Length = ?
Volumen = 0.42 gallons
But we do not need the volume of paint because we know that the wall is squared-shape.
Only we need to know the formula to obtain the area of an square.
Formula area = length²
So 168 = length²
Finally √168 = length
length = 12.96 ≈ 13 ft
