Answer 1

Answers:
i) k is 17
ii) k is 10
iii) k is 48
iv) k is 25
v) k is 24
vi) k is 60

Solutions:
These kind of problems doesn't have any fixed method. The only way to do this is by hit and trial method.

i) 8² = 64
15² = 225

Now 15²-8² = 161, which is square of 12.68. This is not possible.
Now try adding them.
15²+8² = 289, which is square of 17.
So k = 17.

ii) 24² = 576
26² = 676

Subtract and check:
26²-24² = 100, which is square of 10.
So k is 10.

iii) 14² = 196
50² = 2500

Subtract:
50²-14² = 2304, which is square of 48.
So k is 48

iv) 15² = 225
20² = 400

Subtract:
20²-14² = 175, which is square of 13.228. This is not possible.

Now add:
20²+15² = 625, which is square of 25.
So k is 25.

v) 45² = 2025
51² = 2601

Subtract:
51²-45² = 576, which is square of 24.
So k is 24.

vi) 11² = 121
61² = 3721

Subtract:
61²-11² = 3600, which is square of 60.
So k is 60.



I will help for sure. I have given a lot of time for typing this. Thank you. Please mark as brainliest! ☺♥
