what set numbers could represent the lengths of the sides of a right triangle. (a) 9,11,14 (b) 7,24,25 (c) 15, 18,21 (d) 8,9,10
2 answers:
The answer is (B) 7, 24, and 25 This is because 7 squared (49) plus 24 squared (576) makes 625, which is 25 squared. This is Pythagoras' theorem. I hope this helps!
Answer:
Option (b) 7, 24, 25
Step-by-step explanation:
To check the set of numbers that could represent the lengths of the sides of a right angle triangle we will apply Pythagoras theorem to all options.
(a) 9²+11² = 81 + 121 = 202≠ 14²
(b) 7² + 24² = 49 + 576 = 625 = 25²
(c) 15² + 18² = 225 + 324 = 549 ≠ 21²
(d) 8² + 9² = 64 + 81 = 145 ≠ 10²
Looking into all options we can say option (b) is the answer.

There are only 360° in a circle. 453° exceeds one circle. 453° - 360° = 93° This is the standard position of the second circle. The terminal side lies on the second quadrant. The co-terminal angle of the second circle is: 360° - 93° = 267°

1/2 of a mile.
Step-by-step explanation:
He has already gone 4/8 of a mile (3/8 + 1/8) and he needs to go 8/8 of a mile. 8/8 - 4/8 = 4/8. You can simplify that to 1/2.
