Answer:
x=12
Step-by-step explanation:
We know that a right angle is 90 degrees. So we can make the equation Now, we can solve fore X! We can combine 35 and 7 to make the equation
. In order to isolate x we have to subtract 42 from both sides, getting us the equation
Now, in order to isolate x we must divide each side by 4, getting us the equation
. To prove that x=12, we can subsitute x for 12. This means that we can do
which simplified, is 90=90, making x=12 true. Hope this helps :)

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 answer is in the image
