Question

If side a has a length of 3 and side b has a length of 4, use the Pythagorean Theorem to find the length of side c. Round the answer to the nearest tenth.
c =

Answer 1

c^2 = a^2 + b^2
c^2 = 3^2 + 4^2
c^2 = 9 + 16
c^2 = 25
c= 5

answer
c = 5

Answer 2

a^2+b^2= c^2

Plug in a and b.

3^2+4^2= c^2

9+16= c^2

25= c^2

(sqrt) 25

c=5

I hope this helps!
