Ответ:
The ratios are both identical ( 3 over 5 and 3 over 5 )
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that ...
Sin = Opposite/Hypotenuse
sin(x°) = 3/5
and
Cos = Adjacent/Hypotenuse
cos(y°) = 3/5
__
sin(x°) = cos(y°) = 3/5

Step-by-step explanation:
The transformation of the segment AB is:
Given the points of the line segment A'B':
The coordinates of the points A and B in the line segment AB,can be calculated through this procedure:
For A:
x-coordinate:
Substitute the x-coordinate of A' (we can represent it with
) into
and solve for
, which is the x-coordinate of A:
y-coordinate:
Substitute the y-coordinate of A' (we can represent it with
) into
and solve for
, which is the y-coordinate of A:
The point of A is: (-1,0)
For B:
x-coordinate:
Substitute the x-coordinate of B' (we can represent it with
) into
and solve for
, which is the x-coordinate of B:
y-coordinate:
Substitute the y-coordinate of B' (we can represent it with
) into
and solve for
, which is the y-coordinate of B:
The point of B is: (1,0)
