Calculate the missing side length “x”.

1.68?

Step-by-step explanation:

i used trigonometry

Adjacent = cos 62 = A/30

cos 62 x 30 = 14 ( rounded off )

A = 14

X = A = cot 58 = A/14

cot 58 x 14 = 1.68

X = 1.68 ( rounded off )

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
