64°

Step-by-step explanation:

33k-9=90 (being a right angle)

33k=90+9=99

k=99/33=3

CD=20×3+4=64°

arc CD = 64 degrees

Step-by-step explanation:

Find out k value: 33k-9+90=180

33k+81=180

33k=99

k=3

Substitute it in: 20(3)+4=60+4=64

SInce CPD is a central angle, arc CD = 64 degrees

I hope this helped and have a good rest of your day!

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)

the answer is 8/21

hope this
