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

Calculate the distance between the points L=(-4,-1) and E =(3, 7) in the coordinate plane.
BaLLatris [955]

Answer:

10.6301458127

Step-by-step explanation:

Distance between any two points (x1, y1) and (x2,y2)  on a coordinate plane is expressed by the formula = \sqrt{(x1-x2)^2 + (y1 - y2)^2} \\

given  L=(-4,-1) and E =(3, 7

substituting value of coordinates in equation \sqrt{(x1-x2)^2 + (y1 - y2)^2} \\

we have

\sqrt{(-4 - 3)^2 + (-1 - 7)^2} \\=>\sqrt{(-7)^2 + (-8)^2} \\=>\sqrt{49 + 64} \\=>\sqrt{113} \\=>10.6301458127

Therefore  the distance between the points L=(-4,-1) and E =(3, 7) = 10.6301458127
