Step-by-step explanation:
Let find some relationships for angle 7. Looking at a angle near 63, Angle 2.
Angle 7 and Angle 2 are same side consecutive interior angles since they are parallel lines. This means they are supplementary. Keep that in mind.
Angle 2 and the 63 degree angles are vertical angles. This means angle 2 measures 63.
Since angle 2 and angle 7 are supplementary and angle 2 equal 63. We can use substitution method to replace angle 2 with 63. equation.
Angle 7 equal 117

Step-by-step explanation:
1) This Stem and Leaf plot works like a Histogram. Completing the question, check below the Stem plot. Look the data out of the Stem plot and within (in the graph below)
32, 34 , 38 , 39 , 39 , 40 , 43 , 45 , 46 , 49 , 53 , 54 , 57 , 58 , 59 , 59 , 63 , 68
2) Notice how the first digit is on the Stem column (check below)
3) To find the first and Third Quartiles
Let's use the formulas to find the position, then the value. As it follows:
