Please help me with this homework

400 is the hypotenuse

Step-by-step explanation:

20km

Step-by-step explanation:

we need to find c, which is the hypotenuse of the right triangle.

we know the lengths of the legs, which are given as 16km and 12km

you might notice that 16km and 12km can both be divided by 4, which will then give is 4 and 3.

3,4,5 is a pythagorean triple-(the sums of the squares of 3 and 4 is equal to the square of 5).

It can be proved here:

3²+4²=5²

9+16=25

25=25

so that means that c is 5*something

since 12 and 16 are 3*4 and 4*4 respectively, that means that c must be 5*4=20km

Hope this helps!

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
