Please help!!! i need the length of CD

Step-by-step explanation:

looking at the diagram, AC is the hypotenuse, AD is the adjacent and CD is the opposite (based on the position of the angle).

Since you are looking for CD, you would use Sine (SOHCAHTOA). Sine would be opposite over hypotenuse and following the same procedure, you will the cross multiply to get your answer

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
