Answer:
Sure
Step-by-step explanation:
<h3>Answer:</h3>
17
<h3>Explanation:</h3>
The median segment (HJ = 5x+2) has a length that is the average of the lengths of the other parallel segments, (KL = 4x+1, and NM = 27). Writing this relation as an equation, we have ...
... 5x + 2 = (4x + 1 + 27)/2
... 10x + 4 = 4x + 28 . . . . . . multiply by 2, collect terms
... 6x = 24 . . . . . . . . . . . . . . add -4x-4
... x = 4 . . . . . . . . . . . . . . . . . divide by 6
Then the length of KL is ...
... KL = 4x +1
... = 4·4 +1 = 17

Given:
A semicircle.
To find:
Arc length of the semicircle = ?
Solution:
Formula for angle subtended by an arc on the center of circle is given as:
where 
is the arc length and
is the radius of semicircle.
Angle of full circle is 
So, angle of semicircle = 
Using the formula, we can see that:
So, the answer is:
Arc Length of semicircle = or
Answer:
4x-12=8x+12
-24=4x
-6=x
Step-by-step explanation:
put the variables to one side and numbers to the other side
then divide 4 from each side
now you have the answer
