Find the length of the third side. If necessary, round to the nearest tenth.
10
14

≈ 9.8

Step-by-step explanation:

Lets use the Pythagorean theorem.

a^2 + b^2 = c^2.

c is the hypotenuse or the longest side of a triangle.

a and b are the other 2 sides.

10^2 + b^2 = 14^2

10^2 + b^2 - 10^2 = 14^2 - 10^2

b^2 = 14^2 - 10^2

b^2 = 196 - 100

b^2 = 96

b ≈ 9.8
