Answer:
First answer is 22
Second answer is 7
Before I explain the answer, first visualize triangle KJM
angle MKJ is congruent to angle JMR by alternate interior angles, Note how we have 2 angles measures for triangle MKJ.
Next solve for angle KJM using angle sum theorem (all angles in a triangle must equal 180)
72+27+x= 180
x=81
We now know that angle KJM is 81 however the question ask for the other angle created the line segment.
angle KJM - angle KJL
81-56 = angle LJM
22 = angle LJM
Second question
If you know the properties of a parallelogram you should know that its vertices are congruent to itself.
First you solve for x
x+7 = 3x -5
7=2x -5
12=2x
12/2=x
6=x
Next find the value of JL by plugging in the x values
4(6) - 10 = JL
24 - 10 = JL
14 = JL
Finally you divide line JL by half, since line JR and RL and congruent
14/2=JR
7=JR
