There are 360 degrees in the rhombus which means the equilateral triangles has 180 degrees (because it is half the rhombus and also it is the angle sum of a triangle). It is equilateral meaning all sides and angles are the same so they all must be 60 (180/3)
Now this must mean that angle a is equal to the opposing angle being 60

To describe a sequence of transformations that maps triangle ABC onto triangle a"b"c", a student starts with a reflection over t
Paha777 [63]

i dont quite get the question but...

i guess this is how it is.

Take the mirror image of∆ABC Through the a line through the point y=3.

The new ∆ABC would have point C=(4,2)

B=(3,-6) A=(1,-3)

Now shifting the ∆ABC one unit (<em>i.e. 2 acc. to the graph as scale is 1 unit =2</em>) towards right ( or <em>adding 2 to the x coordinates of ∆ABC)</em>

We get the Coordinates of triangle ABC as A=(3,-3) B=(5,-6) C=(6,2).

This coordinate is the same coordinates of ∆A"B"C".

Hope it helps...

SSSSS [86.1K]

Answer: There are 12 pairs of tennis shoes.

Step-by-step explanation:

Since we have given that

For each pair of tennis shoes , she owns 4 pairs of flip flops,

so their ratio will be 1:4

Let the number of tennis shoes be x

Let the number of flip flops be 4x

According to question,

4x-x=9

3x=9

x=\frac{9}{3}

x=3

So, the number of pairs of tennis shoes is given by

4x=4\times 3=12

Hence, there are 12 pairs of tennis shoes.
