The International Space Station orbits Earth at an altitude of about 240 miles. In the diagram, the Space Station is at point E. The radius of Earth is approximately 3,960 miles. To the nearest ten miles, what is EH, the distance from the space station to the horizon?

are there options ?

Step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
