The measure of the angle JL is 33 degrees
Bisection of anglesA bisection is a line that divides an angle into two equal portion. Using the addition postulate below:
<JKM = <JKL + <LKN + <NKM
If the line KN bisects <LKM then <LKN = <NKM = 22 degrees
Substitute the given parameters
<JKM = <JKL + <LKN + <NKM
77 = <JKL + 22 + 22
77 = <JKL + 44
<JKL = 77 - 44
<JKL = 33 degrees
Hence the measure of the angle JL is 33 degrees

The statement can be proved by the law of syllogism.
A formal logical framework used to infer a conclusion from a series of premises is referred to as a syllogism, also known as a rule of inference.
The law of syllogism in conditional statement is given as:
if p then r and if r then q , then we can state that if p then q , where p , q, and r are statements.
Now in the given conditional statements we can write it as:
let p = You go camping
r = you will need a flashlight
q = you will need extra batteries.
Now it is given the if p then r and again if r then q , so by using the law of syllogism we can state that if p then q , that is

Carolyn needs to figure out the missing properties used to simplify the expression below
The properties used in the the simplification of the expression is:
step 1: Inverse multiplication property
step 2: Commutative property
step 3: Associative property
step 4: Commutative property
step 5: Identity property
Given the expression is:
1 ÷ 2/3 × (₋5) × 3 ÷ (₋1/4)
step 1: 1 × 3/2 × (₋5) × 3 × (₋4)
Inverse multiplication property is applied.
The reciprocal of a particular integer is referred to as the multiplicative inverse. It is employed to make mathematical expressions simpler. The word "inverse" denotes an opposing or opposed action, arrangement, position, or direction. A number becomes 1 when it is multiplied by its multiplicative inverse.
step 2: 1 × (₋4) × 3/2 × (₋5) × 3
Commutative property is applied.
Mathematical addition and multiplication operations are covered under the commutative property. In other words, adding or multiplying two integers does not change the outcome if the order or location of the numbers is changed.
step 3: 1 × [(₋4) × 3/2] × (₋5) × 3
Associative property is applied.
According to the associative feature of multiplication, the outcome of a multiplication problem is unaffected by the arrangement of the numbers in the problem's constituent parts.
step 4: 1 ×[-6] × (₋5) × 3
commutative property is applied.
step 5: (-6) × (₋5) × 3
Identity property is applied.
Multiplying 1 by any number yields the number itself, according to the Multiplicative Identity Property, commonly known as the Identity Property of Multiplication. This is because any time a number is multiplied by 1, it retains its identity and does not change.
Hence we have applied the above mentioned properties of multiplication.

What are Collinear Points?When two or more points are on a straight line, they are classified as collinear points.
What is the Midpoint of a Segment?The point on a line segment that bisects the segment into two equal parts is referred to as the midpoint of the line segment.
We are given that:
LM = MP, since, points L, M. and P are collinear points, therefore, it implies that point M is the midpoint of segment LP.
It also means that M bisects segment LP since LM = MP, where M is the midpoint of segment LP.
Thus, the statement that is false about the relationship of L, M, and P that are collinear is: 3. LM + MP = 180.

The total weight of the two animals is 1.2 x 10^5 lbs
How to determine the total weight of the two animals?The given parameters are
Animal 1 = 5.36 x 104 lbs.
Animal 2 = 6.2 x 104 lbs
Rewrite the parameters properly
Animal 1 = 5.36 x 10^4 lbs.
Animal 2 = 6.2 x 10^4 lbs
The total weight of the two animals is calculated as
Total weight = Animal 1 + Animal 2
This gives
Total weight = 5.36 x 10^4 lbs + 6.2 x 10^4 lbs.
Factor out 10^4 lbs
Total weight = (5.36 + 6.2) x 10^4 lbs.
Evaluate the sum
Total weight = 11.56 x 10^4 lbs.
Rewrite as
Total weight = 1.156 x 10^5 lbs.
Approximate
Total weight = 1.2 x 10^5 lbs.
Hence, the total weight of the two animals is 1.2 x 10^5 lbs
