Hello,

The answer should be "8=m".

Reason:

Since it takes 8 minutes to run 1 mile put that first:

8

Since how 8min equal 1 mile you put equal

8=

Since how it could be more miles but m

8=m

If you need anymore help feel free to ask me!

Hope this helps!

How is the formula for a triangle derived from a parallelogram? Please give a good explanation.
Katen [24]

Answer:

At first, we divide the parallelogram into two triangles by joining any two opposite vertices. These two triangles are exactly the same (congruent) and thus have equal areas. The area of the parallelogram is the summation of the individual areas of the two triangles. We drop a perpendicular from a vertex to its opposite side to get an expression for the height of the triangles. The area of the individual triangle is 12×base×height12×base×height .The area of the parallelogram being twice the area of the triangle, thus becomes after evaluation base×heightbase×height .

Complete step by step answer:

The parallelogram can be divided into two triangles by constructing a diagonal by joining any two opposite vertices.





In the above figure, ΔABDΔABD and ΔBCDΔBCDare the two such triangles. These two triangles have:

AB=CDAB=CD (as opposite sides of a parallelogram are equal)

AD=BCAD=BC (opposite sides of a parallelogram are equal)

BDBD is common

Thus, the two triangles are congruent to each other by SSS axiom of congruence. Since, the areas of two congruent triangles are equal,

⇒area(ΔABD)=area(ΔBCD)⇒area(ΔABD)=area(ΔBCD)

Now, we need to find the area of ΔABDΔABD . We draw a perpendicular from DD to the side ABAB and name it as DEDE . Thus, ΔABDΔABD is now a triangle with base ABAB and height DEDE .

Then, the area of the ΔABD

Geometry help please
8_murik_8 [283]
To find the slope of a line that is perpendicular to the given line, we find the negative reciprocal of the given slope (flipped and made negative), so ½ would become -2/1 or simply -2. This gives us the equation y=-2x+b. To find b we plug in the coordinates the new line has to pass through, so ((-5)=-2(10)+b) = (-5=-20+b) = (15=b) or (b=15). So, the answer would be A. y=-2x+15
