Which of the following can be the sides of a right angled triangle?
8, 17, 15
7, 8, 9
1, 3, 6
8, 10, 5
We have 172 = 289 and 82 + 152 = 64 + 225 = 289
This give 172 = 82 + 152
Therefore, 8, 17, 15 are the sides of a right angled triangle.
Question 94
Solve the following question:
Can a right-angled triangle with sides 6 cm, 10 cm and 8 cm be formed? Give reason.
Re-arrange suitably and find the sum in each of the following :
(i)1112+−173+112+−252
(ii)−67+−56+−49+−157
(iii)35+73+95+−1315+−73
(iv) 413+−58+−813+913
(v)23+−45+13+25
(vi) 18+512+27+712+97+−516
