Question

Find the length of a missing side of the triangle around your nearest tenth​

Answer 1

missing side = 11.5

Explanation:

`a^(2) = c^(2) - b^(2)`

`a^(2) = 14^(2) - 8^(2)`

`a^(2) = 196 - 64`

`a^(2) = 132`

`\sqrt{a^(2) } - √(132)`

a = 11.489

round to the nearest tenth:

11.489 = 11.5

Answer 2

Using the Pythagorean theorem:

14^2 = 8^2 + x^2

196 = 64 + x^2

Subtract 64 from both sides:

132 = x^2

Take the square root of both sides:

X = 11.49

Rounded to nearest tenth = 11.5
