IF K is the midpoint of JL then JK = KL, so...
5x + 1 = 7x - 3
5x = 7x - 4
-2x = -4
x = 2
JK = 5(2) + 1 = 11
JL = 2 * JK = 2 * 11 = 22
12*9=108
5*7=35
108+35=143.
Hope this helped☺☺
The limit of
as x approaches negative 3 is 1
<h3>Limit of a function </h3>
The limit of the function given in question can also be written as:

To determine the required limit, we will simply substitute the value of x into the function as shown:

Answer:
30,60,90
Step-by-step explanation:
triangle are in the ratio 1:2:3.
So
Angles=X,2x,3x
X+2x+3x=180
6x=180
X=180/6
X=30
So angles are 30,60,90
