Question

Find the length of the missing side of the triangle to the nearest tenth.​

Answer 1

a = 18.8

Explanation:

With it being a right angle, you can use the pythagorean theorem equation.

`a^(2) + b^(2) =c^(2) \\a^(2) + 18^(2) =26^(2) \\a^(2) +324 = 676\\a^(2) = 676 - 324 \\a^(2) = 352\\a = √(352) \\a = 18.76 = 18.8`
