Find the measurement of arc JL
PLLLLLLSSSS HELP 100 points
1 answer:
Answer:
108
Step-by-step explanation:
Hey There!
So the arc is equal to its corresponding angle
We are given the angle of KL which is 30 so all we need to do is find the length of arc JK
The angles given and the missing angle are supplementary angles meaning that they will add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-30-72=78
Now we just add arc JK and arc Kl
30+78=108
so arc JL is equal to 108

Because K is the midpoint of JL and JK = 18, KL must also equal 18. So the equation would be 3x - 15 = 36 because you add 18 + 18. You then add 15 to both sides to get 3x = 51. Then you divide by 3 on both sides to get x = 17.
Answer:
7×10=70
area = length × width
Thats hard bro hopefully somebody helps you figure it out
8/14 12/21 16/28 these are some of the fractions that came to mind
It’s -11 becuase i just took the test and got it
