Answer:
c) 5
Step-by-step explanation:
In this question you are being asked to find the hypotenuse of the triangle
the triangle has one side that is 3 and the other is 4
use Pythagoras to find the missing side (a^2+b^2=c^2)
3^2+4^2=c^2
simplify the exponents
9+16=c^2
combine like terms/adding
25=c^2
take the square root
5=c
the length of the hypotenuse is 5
