The capital letter that shows an example of perpendicular line segments is: A. L (see attachment).
<h3>What are Perpendicular Line Segments?</h3>
Perpendicular line segments are lines or rays that intersect at a point to form right angles (angle 90 degrees) at their point of intersection.
When two lines intersect, and at their point of intersection, the angle formed is a right angle, then both lines are perpendicular line segments just like the lines that forms letter L as shown in the diagram attached below.
Therefore, the capital letter that shows an example of perpendicular line segments is: A. L (see attachment).

Answer:
a) ∠TVZ= 95°
Step-by-step explanation:
3a) ∠STY= ∠QTV (vert. opp. ∠s)
3x°= 120°
x°= 120° ÷3
x°= 40
∠TVZ= ∠RVW (vert. opp. ∠s)
∠TVZ= (2x +15)°
∠TVZ= [2(40) +15]°
∠TVZ= (80 +15)°
∠TVZ= 95°
b) Since ∠TVZ and ∠WVZ lies on a straight line,
∠TVZ +∠WVZ= 180° (adj. ∠s on a str. line) -----(1)
∠WVZ= (2x +5)°
∠WVZ= [2(40) +5]°
∠WVZ= (80 +5)°
∠WVZ= 85°
Substitute ∠WVZ= 85° into (1):
∠TVZ +85°= 180°
∠TVZ= 180° -85°
∠TVZ= 95°
Thus, ∠TVZ is indeed 95°.
Notes:
• What is vert. opp. ∠s?
It is an abbreviation used for a property of angles, vertically opposite angles. When two lines intersect each other, the angles facing each other (or the angles on the opposite side of each other) are equal.
• What is adj. ∠s on a str. line?
It is an abbreviation for 'adjacent angles on a straight line'. The sum of all the angles on a straight line is 180°.

Step-by-step explanation:
If you would like to calculate 2/3 * m - 1 1/6 + 5/6 * m - 1 1/3, you can do this using the following steps:
2/3 * m - 1 1/6 + 5/6 * m - 1 1/3 = 4/6 * m - 7/6 + 5/6 * m - 4/3 = 9/6 * m - 7/6 - 8/6 = 3/2 * m - 15/6 = 1 1/2 * m - 5/2 = 1 1/2 * m - 2 1/2
The correct result would be 1 1/2 * m - 2 1/2.
