Two parallel lines are crossed by a transversal. What is the value of k? k = 9 k = 20 k = 60 k = 71
1 answer:
your question seems missing the figure.
I am attaching the required figure below.
You can study the correct answer to your question and complete explanation with the figure below.
Answer:
k=60
Step-by-step explanation:
When a pair of parallel lines is crossed by a transversal, it will make 8 angles, pairs of vertical/opposite angles, two pairs of acute angles and two pairs of obtuse angles. All acute angles are congruent as well as all obtuse angles are congruent. Simply we can say that pairs of acute angles and pairs of obtuse angles are congruent.
From the figure attached below (by the name "Pairs of parallel lines crossed by a transversal"), we get the following equations as:
2k+11=131
Solving for k, we get
2k=131-11
2k=120
k=120/2
k=60

The given expression is
This can be simplified as :
=
We know that:
Similarly we also can simplify:
So our expression will look like this:

This can also be written as:
So the Answer is Option B
14gallons=380miles
14/380=<span>0.03684210526gallons/mile
</span>
418*<span>0.03684210526=15.4gallons
</span>
or you could cross multiply
14gallons=380miles
x gallons=418miles
380x=5852
divide both sides by 380
x=15.4 gallons
14/380=<span>0.03684210526gallons/mile
</span>
418*<span>0.03684210526=15.4gallons
</span>
or you could cross multiply
14gallons=380miles
x gallons=418miles
380x=5852
divide both sides by 380
x=15.4 gallons
