let : y = Opponent side, x= Adjecent side

and r= hypotenuse

tan = 4/5

y/x = 4/5 => y =4, x=5

so, r = √4²+5²=√16+25=√41

sin = y/r = 4/ √41

cos = x/r = 5/√41

tan = y/x = 4/5

csc = r/y = √41 /4

sec = r/x = √41 /5

cot = x/y = 5/4

oksian1 [2.3K]

Answer: Undefined

Step-by-step explanation:

In geometry there are three  undefined terms that we use to define other terms:

  • Point → In geometry a point has a location but no dimension.
  • Plane →  A plane extends is a 2-dimensional surface that extends infinitely on both sides.
  • Line → A line is a one-dimensional undefined figure that extends infinitely in both the directions. It has length but has no width.

Hence, the correct option is "Undefined".

What is the equation of the line that is parallel to the line y - 1 = 4(x + 3) and passes through the point (4, 32)?
Monica [59]

Answer:

y = 4x + 16

Step-by-step explanation:

y - 1 = 4(x + 3)

Has a slope of 4

y = 4x + c

32 = 4(4) + c

32 - 16 = c

c = 16

y = 4x + 16
