A = 5, b = 12, c =

a.√ (34)

b.√ (119)

c.√ (154)

d. 13

d. 13

Step-by-step explanation:

From my understanding, this is the Pythagoras theorem.

Pythagoras theorem: c² = a² + b²

a = 5

b = 12

c = ?

c² = a² + b²

c² = 5² + 12²

c² = 25 + 144

c = √169

c = 13

Therefore option d is the right answer.
