Points e, f, and d are located on circle c the measure of arc ed is 68°. what is the measure of angle efd?

The measure of ∠EFD is 34°

Step-by-step explanation:

Given that points E, F, and D are located on circle C. The measure of arc ED is 68°. we have to find the measure of angle EFD.

By theorem,

The angle at the center is twice the angle at the circumference of circle.

i.e ∠EOD=2∠EFD

⇒

⇒

⇒

Hence,the measure of ∠EFD is 34°

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things
