GivenR is the midpoint of SQ and PTTo proveΔPQR ≅ ΔTSRSolutionR is the midpoint of SQ
SR = 1/2SQ and RQ = 1/2SQ ⇒ SR ≅ RQR is the midpoint of PT
PR = 1/2PT and RT = 1/2PT ⇒ PR ≅ RTSQ and PT intersect at point R ⇒
∠PRQ ≅ ∠TRS as vertical anglesTriangles PQR and TSR have two sides and the included angle congruent, therefore:
ΔPQR ≅ ΔTSR,as per SAS congruence postulate
If two sides and the included angle in one triangle are congruent to two sides and the included angle in another triangle, then the two triangles are congruentRelated Questions

Trisha has $100 to spend on presents for 4 of her friends. She wants to spend the same amount on each friend. How much money can she spend on each friend (x)?
*Choose the inequality that best matches this scenario.
a. 4+x ≤ 100
b. 4x ≤ 100
c. x ÷ 100 ≥ 4
d. 100 - x ≥ 4
Answers
Answer:
B
Step-by-step explanation:
Trisha has $100. So she has to spend less than $100 or exactly 100 on her friends. The sign to represent this is ≤ ( the less than or equal to sign )
so if she has 4 friends and wants to spend x on each friend, she would spend a total of 4x on her 4 friends.
Remember that she has to spend less than or equal to $100. The equation to represent this is 4x ≤ 100

To make 3 litres of pale purple paint you mix:
1.5 litres red
1.25 litres of blue
0.25 litres of white paint.
a How much red paint is needed to make 8 litres of paint?
Answers
Answer:
We need 4 litres of red paint.
Step-by-step explanation:
We need to take their respective precentages to compare the 3 litres of paint to 8 litres of paint.
[tex] \frac{1.5}{3} \times 100\% = 50\% \\ \frac{1.25}{3} \times 100\% = 41.67\% \\ \frac{0.25}{3} \times 100\% = 8.33\% \\ [/tex]
Now, we know that the pale purple paint contains 50% red paint, 41.67% blue paint, and 8.33% white paint.
Now, we will transfer these percentages to the 8 litres of paint:
[tex]50\% \: of \: 8 \: litres = 0.5(8) = 4 \: litres \\ 41.67\% \: of \: 8 \: litres = 0.4167(8) = 3.3336 \: litres \\ 8.33\% \: of \: 8 \: litres = 0.0833(8) = 0.6664 \: litres[/tex]
whats all the fractions that are eqvalent to 4/3
Answers
Answer:8/6,12/9
Step-by-step explanation:
The fraction 8/6 is equal to 4/3 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (4/3) by any interger number, ie, multiply by 2, 3, 10, 30... 8/6 is equivalent to 4/3 because 4 x 2 = 8 and 3 x 2 = 6 12/9 is equivalent to 4/3 because 4 x 3 = 12 and 3 x 3 = 9
Answer:
4/3 = 8/6 = 12/9 = 16/12

Arya deals in clothing and accessories. She bought 10 shirts at a wholesale price of 1120 each and sold them
all at a profit of 40 percent.
What was the price Arya charged for the 10 shirts?
Answers
Answer:
15680
Step-by-step explanation:
Cost of 1 shirt: 1120
Cost of 10 shirts: 11200
Add 40% to the cost of 10 shirts:
40% + 100% = 140% = 1.4
1.4 * $11200 = 15680
Answer: 15680
Solve for x: 2/5=4/x
Answers
Explanation: First you cross-multiply to get 2x=20 and then divide by 2 to get x=10
9514 1404 393
Answer:
x = 10
Step-by-step explanation:
Using your number sense, you recognize that a fraction equivalent to 2/5 that has 4 in the numerator is 4/10. This tells you x = 10.
__
The usual instructions for solving this algebraically are to "cross multiply", then divide by the coefficient of x.
2/5 = 4/x . . . . given
2x = 20 . . . . . multiply by 5x on both sides
x = 10 . . . . . . . divide by 2
__
You can do the above two steps both at once: multiply by 5/2x.
(2/5)(5/2x) = (4/x)(5/2x)
x = 20/2 = 10

If the shortest side of a right triangle is 19, what are the lengths of the other TWO sides
that makes the side lengths a Pythagorean triple? HELP ASAP PLZ
Answers
Answer:
180 and 181
Step-by-step explanation:
A pythagorean triple basically refers to numbers that satisfies the pythagorean theorem. This theorem states that the square of the hypotenus (a) of a right angle triangle is equal to the sum of the squares of the other two sides (b and c).
That is;
a² = b² + c²
If the shortest side is 19, the other two sides are 180 and 181.
The hypotenus is the longest side of the right angle triangle.
Check:
181 = 180 + 19
181² = 180² + 19²
32761 = 32400 + 361
32761 = 32761
