16. Triangle JKL and triangle PQR are shown above. If ∠J is congruent to ∠P, which of the following must be true in order to prove that triangles JKL and PQR are congruent? A. ∠L ≅ ∠R and JL = PR B. KL = QR and PR = JL C. JK = PQ and KL = QR D. ∠K ≅ ∠Q and ∠L ≅ ∠R

Answer: A. $\angle L \equiv \angle R$ and $JL = PR$ Explanation: To prove that triangles $JKL$ and $PQR$ are congruent, we can use the Angle-Side-Angle (ASA) Congruence Theorem. This theorem

Pedro is going to use SAS to prove that △PQR ≅ △SQR. Which of these is a necessary step in Pedro’s proof? O A. Prove that ∠QPR ≅ ∠QSR by the Isosceles Triangle Theorem. O B. Prove that QR ≅ QR by the reflexive property. O C. Prove that PQ ≅ SQ by CPCTC. O D. Prove that ∠PQR ≅ ∠SQR by vertical angles.

Answer: B. Prove that $ \overline{QR} \cong \overline{QR} $ by the reflexive property. Explanation: To use the Side-Angle-Side (SAS) congruence theorem, we need to show that two sides and the included

2) Mr Lim gave 3600 to his wife and two children altogether. His wife received 500 more than his son. His son received twice as much as his daughter. How much did Mr Lim’s wife received? (W.Bk 5A : pg 28 #6)

Answer: Mr. Lim’s wife received $1,700. Explanation: To solve this problem, we use algebraic equations to represent the relationships and total amount given. We define variables for the amounts received by

P S 22° Q R If ∠PQR measures 75°, what is the measure of ∠SQR? ① 22° ② 45° ③ 53° ④ 97°

Answer: 53° Explanation: The problem involves the concept of the sum of angles around a point. Since $ \angle PQR $ and $ \angle SQR $ are adjacent angles forming a

Which of the following is equivalent to the expression below? 7^8.27 A. 7^8 7^27/100 B. 7^8 7^2/10 7^7/100 C. 7^8 7^27/10 D. 7^8 * 7^2/10 + 7^7/100

Answer: C. $ 7^6 \cdot 7^{27/100} $ Explanation: The expression $ 7^{6.27} $ can be rewritten using the properties of exponents. Specifically, the expression can be split into two parts: the

4 A radio station is giving away tickets to a play. They plan to give away tickets to seats that cost 10 or 20. They plan to give away at least 20 tickets, and the total cost of all the tickets can be no more than $300. Make a graph showing how many tickets of each kind can be given away. x + y ≥ 20 10x + 20y ≤ 300

Answer: The solution involves graphing the system of inequalities: $ x + y \geq 20 $ and $ 10x + 20y \leq 300 $. Explanation: This problem involves linear inequalities and
