Answer:

C=20 units (They didn't give the unit in the problem so if you want just write 20.)

Step-by-step explanation:

You need to solve for c. So first you have to use the equation.

We already know a and b so no we plug them in.

16^2 + 12^2 = c^2

When a number is squared or written as to the power of two you simply have to multiply that number by itself. So 16^2=256 and 12*12=144

256+144=c^2

c^2=400

Now we have to do another step because we don't want to know c^2 but want to know c. Now we have to find the square root of 400. The answer is 20 because 20*20=400.

Graph ΔABC and its image after a rotation of 180º about the origin.

ValentinkaMS [17]

Answer:

The vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5). The graph of image and preimage is shown below.

Step-by-step explanation:

From the given figure it is noticed that the vertices of triangle ABC are A(0,0), B(1,5) and C(-4,5).

If a figure rotated at 180º about the origin, then

$P(x,y)\rightarrow P'(-x,-y)$

The vertices of image are

$A(0,0)\rightarrow A'(0,0)$

$B(1,5)\rightarrow B'(-1,-5)$

$C(-4,5)\rightarrow C'(4,-5)$

Therefore the vertices of image are A'(0,0), B'(-1,-5) and C'(4,-5).

The graph of image and preimage is shown below.
