For a perpendicular bisector
There are two rules.
1) It is perpendicular to the segment so it makes an angle of 90°
2) It divides the segment in two equal parts or it passes through the midpoint of the segment.
As RS is the perpendicular bisector of PQ.
So T is the midpoint
m<PTR = 90° is true
T is the midpoint of PQ is true.
RS is the perpendicular bisector of PQ is false
RS ⊥ PQ is true
RT = ST is false
PT = QT is true
A, B, D & F are true.
This triangle can be classified as an Acute Scalene Triangle.
It is an Acute triangle because all of its sides are acute (less than 90 degrees)
It is a Scalene triangle because all of its sides are of different lengths.
To find the missing angle degree we must subtract 61 and 78 from 180. We subtract them from 180 because all angles of a triangle add up to 180 degrees.
180 - 61 - 78 = 41.
So the missing angle (x) = 41 degrees.

He would need to work 8 hours. 168/12=14. 14x8=112.
Answer:
- <u><em>Sometimes.</em></u>
Explanation:
The statement is <em>P forward Q is true and q is true, then p is true sometimes always or never.</em>
<em />
That, written using logical symbology, is:
- p → q,
- q is true
- then p is ?
p → q is known as a conditional statement.
When the conditional p → q is true and p is also verified to be true, you must conclude that q is (necessarily) true (else the conditional would be false).
That also means that if q is verified to be false (not true), p must necessarily be false (else the conditional would be false).
Nevertheless, the fact that q is true, does not permit to conclude whether p is true or false: p can be either true or false when you only know that q is true.
Then, you cannot tell that p is true always or never; some times it could be true and others false.
