Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ².
<h3>What is Pythagorean theorem?</h3>
Pythagorean theorem is a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.
Mathematically, Pythagorean's theorem is given by this formula:
x² + y² = z²
Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ². It is given that x² + y² = z² in triangle ABC, so z² = PQ² or AB = PQ.
The above information shows that the triangles are congruent because their three (3) sides are congruent. Therefore, to show that triangle PQR is a right triangle, we can use corresponding parts of the congruent triangles to show that PQ = AB, PR = AC and QR = BC.

Answer:
70 minutes
Step-by-step explanation:
3 1/2 ÷1/4= 14 ×5= 70
so you first make 3 1/2 to an improper fraction, then you find the greatest common denominator between 7/2 and 1/4 which is 4, so you multiple 7/2 by 2 and get 14/4 and divide that by 1/4 and get 14minutes now multiply that by 5 laps and receive 70 minutes.
Answer:
Commission received by Edison =$15112
Step-by-step explanation:
It is given that,
Edison has a sales job and receives $45,448 as his annual pay, plus commission.
His company pays him a commission of 15% on his total sales.
He makes sales of $25,000 in the first 3 months,
The commission paid for those month is 15% of $25,000
Commission = (15 x 25,000 )/100 =$ 3750
<u>To find amount paid for 3 months </u>
Amount = 45,448/4 = $11362
he will be paid for those 3 months =11362 + 3750 = $15112
