Question

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

Answer 1

Explanation:

to find this we'll use Pythagoras theorem which is
`a^(2) +b^(2) =c^(2)`

here a is the perpendicular, b is the base and c is the hypotenuse (the side opposite to the 90 degree angle)

a^2+11^2=16^2

a^2+121=256

a^2=256-121

a^2=135

`\sqrt{a^(2)} =\sqrt{135`

a= 11.6 units

Answer 2

x=11.6

Explanation:

Pythagorean Theorem

11²+x²=16²

121+x²=256

x²=256--121

x²=135

x=√135

x=11.6189
