The picture shows a triangular island: A right triangle is shown with an acute angle equal to 45 degrees. The length of the side of the triangle opposite to the acute Which expression shows the value of c? (1 point) Select one: a. b over tan 45 degrees b. b over cos 45 degrees c. a cos 45° d. a tan 45°

d. a tan 45°

Step-by-step explanation:

if c is the opposite and a is the adjacent

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
