Find the length of the third side. If necessary, round to the nearest tenth.
4

Answer:
x=2.6
Step-by-step explanation:
We can use the Pythagorean theorem to find the third side
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
3^2 + x^2 = 4^2 where x is the unknown side
9 + x^2 = 16
Subtract 9 from each side
x^2 = 16-9
x^2 = 7
Take the square root of each side
sqrt(x^2) = sqrt(7)
x =2.645751311
Rounding to the nearest tenth
x = 2.6
Answer:
2.65
Step-by-step explanation:
take the length of the third side as x
so,take Pythagoras theorem
4^2=3^2+x^2
16=9+x^2
x^2=16-9
x^2=7
x=√7
x=2.645
x=2.65
