The problem ask to choose among the following choices the side do the angles PQR and angle RQS have in common where as both of them are an adjacent angles and the best answer would be QR and RQ. I hope you are satisfied with my answer and feel free to ask for more
SAS theorem states that if <u>two sides</u> and the <u>included angle</u> of one <u>triangle</u> are <u>congruent</u> to <u>two sides</u> and the <u>included angle</u> of another <u>triangle</u>, then these two <u>triangles are congruent</u>.
1. RQ ≅ QP (given)
2. If RP bisects ST at Q, then TQ ≅ QS (by the definition of segment bisector).
3. ∠RQT, ∠PQS are vertical angles (angles that are vertically opposite to each other when lines PR and ST intersect, Q is the common vertex).
∠RQT ≅ ∠PQS (by the vertical angles theorem).
Vertical angles theorem states that vertical angles are always congruent.
According to SAS theorem, ΔRQT ≅ ΔPQS.
Answer: vertical angles theorem

Answer:
The half life of the car is 3.98 years.
Step-by-step explanation:
The value of the car after t years is given by the following equation:
In which V(0) is the initial value and r is the constant decay rate, as a decimal.
The value of a certain car decreases by 16% each year.
This means that
So
What is the 1⁄2-life of the car?
This is t for which V(t) = 0.5V(0). So
The half life of the car is 3.98 years.
