What is the value of x which proves that the runways are parallel? what is the measure of the larger angle? a) x = 20; 92 degrees b) x = 40; 88 degrees c) x = 25; 107 degrees d) x = 30; 115 degrees

The answer is C) x = 25; 107 degrees

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

i just took the test, the correct answer is .. 31.5 in.
