If two triangles are similar, it means that one is the scaled version of the other.
In similar triangles, correspondant angles are the same, and correspondant lengts are all in the same ratio
. The ratio between the areas is
.
So, for example, if the scale ratio is
, all sides of the new triangle are twice as long as the sides of the old one, and the area of the new one is
times the area of the old one.
Since in this case the two areas are equal, their ratio is
. This implied that also
, which means that also correspondant sides are equal.
In other words, these two triangles are not only similar, but congruent. This means that, in particular, all correspondant sides have same length, so the longest side of ABC has a length of 25 as well.
Answer:
4) is the opposite function of 3), and vice versa. Because f(x) =2x-1 and its opposite f(x)=-2x+1. And we can see them both in pictures 3 and 4.
Step-by-step explanation:
A piecewise function is a function defined in a sequence of intervals. The most known piecewise function is the modular function. (1st picture)
An opposite function is given by f(x)=-x of f(x)=x
The following pictures describe the following functions:
1) f(x)=-|2x|+2
2) f(x)= 2.34x-2.34 and f(x)= -2.34x-2.34
Notice how the second function express the opposite line, by the opposite angular coefficient.
3) f(x) =2x-1 and f(x)=-2x+1
4) f(x) = -2x+1 and f(x)=2x-1
Different intervals but the same functions are graphed in 3 and 4. So the graph of f(x)=2x-1 and its opposite f(x)=-2x-1
X=75 because the other angle is a corresponding angle
Answer:
25 is the answer
Step-by-step explanation:
yup.
