A polygon has the following coordinates: A(3,1), B(5,3), C(2,5), D(-1,5), E(-4,3), F(-2,1). Find the length of DC.
nlexa [21]
To find the length of a line given two points, we are going to use the distance formula, which is defined below:
(
and 
are the two points)
The points in this problem are (2, 5) and (-1, 5). We can find the distance of DC by substituting these values into the distance formula and simplifying, as shown below:
- Substitute values into formula
- Combine like terms and then simplify
to 0
- Compute
- Compute
The length of DC is 3.
You dont there is no way to. You just say 70x114=7980

Answer:
8 and 4
Step-by-step explanation:
You find half of the sum and subtract half of the differece for 6 and the other 6 you add the hal of the difference.
The height of the trre will be given by:
tan θ=(opposite)/(adjacent)
θ=52°
Adjacent= distance of the golfer to the tree= 10 ft
opposite = height, h, of the tree
thus
tan 52=h/10
hence solving for h we get:
h=10tan52
h=12.799~12.8 ft
