Answer:
No it does not form a triangle.
Step-by-step explanation:
If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.
Answer:
(a) 150
(b) 384
(c) 84
(d) 261
(e ) 480
Step-by-step explanation:
(a)
Let 'a' be a number such that the half of his third is 25; i.e.
Hence, the number is 150.
(b)
Let 'b' be the number such that the quarter of his half is 48 i.e.

Hence the number is 384.
(c)
Let 'c' be the number such that the third quarter or, increased by 17 is 80.

Hence, the number is 84.
(d)
Let 'd' be the number such that its triplet, reduced by 28 is 755

Hence the number is 261.
(e
Let 'e' be the number such that double his third, increased by 80 is 400.

Hence, the value of the number is 480.
