Correct Answer: 33, 44, 55
Explanation:
A Pythagorean triple consists of three positive integers a, b, and c, such that a² + b² = c².
Here we know, that 3, 4, 5 are pythagorean triplets as 25 = 9 + 16. Hence, its multiple will also be a pythagorean triple.
In the options given, (3 x 11 , 4 x 11 , 5 x 11) = 33, 44, 55 is a pythagorean triplet.
Correct Answer: Complimentary angles
Explanation:
Complimentary angles are those two angles whose sum is 90 whereas two angles whose sum is 180 are called Supplementary angles.
Correct Answer: 1/7
Explanation:
Multiplicative inverse is nothing but a reciprocal of a number.
It is defined as one of a pair of numbers that when multiplied with another number equals the number 1.
Multiplicative inverse or reciprocal of 7 is
7 x n = 1
=> n = 1/7.
Hence, Multiplicative inverse or reciprocal of 7 is 1/7.
Correct Answer: 1
Explanation:
The product of a number and its reciprocal is always equals to 1.
For Example : Let the number be 4.
Now, its reciprocal is 1/4
Hence, required product = 4 x 1/4 = 1.
Now, take the number as -15.
Then its reciprocal is -1/15
Required product = -15 x -1/15 = 1.
Hence, the product of a number and its reciprocal is 1.
Correct Answer: is described generally, not using a formal definition
Explanation:
In geometry, we can define plane as a flat surface with no thickness.
The surface extends with no ends.
A plane does not have any edges even if we draw it on paper with edges, it does't mean it has edges.
Hence, A plane is an undefined term because it is described generally, not using a formal definition.
Correct Answer: 0
Explanation:
A tangent contains ZERO chords, as it touches the circle at only one point.
Hence, it does not contain any chord.
Correct Answer: Sona
Correct Answer: + and ?
Correct Answer: 190
Correct Answer: 5
