n200080 [17]

Answer:

5/13, 12/5, 12/13

Step-by-step explanation:

cos = adj/hyp

tan = opp/adj

sin = opp/hyp

hyp = 13

adj = 5

opp = 12

Plug in.

cos = 5/13

tan = 12/5

sin = 12/13

line cd passes through points c(3, –5) and d(6, 0). what is the equation of line cd in standard form? 5x 3y
SOVA2 [1]

The equation of the line CD that passes through points C(3 , -5) and D(6 , 0) is 5x - 3y - 30 = 0.

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

The two-point form of the equation of a line can be used to form the equation of a line if two points are given.

(y-y_{1} )=\frac{y_{2} -y_{1} }{x_{2} -x_{1}} (x-x_{1} )

Substituting the values,

(y--5 )=\frac{0 --5 }{6 -3} (x-3)

(y+5 )=\frac{5 }{3} (x-3)

(y+5 )=\frac{5 x}{3} -5

3(y+5 )=5x -15

3y+15=5x -15

3y=5x-30

Meanwhile, the standard form of equation of a line is ax + by + c = 0, where a and b are the coefficients, x and y are the variables, and c is the constant term.

5x - 3y - 30 = 0
