Question

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

Answer 1

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

Answer 2

Answer:

missing side = 11.5

Step-by-step explanation:

$a^{2} = c^{2} - b^{2}$

$a^{2} = 14^{2} - 8^{2}$

$a^{2} = 196 - 64$

$a^{2} = 132$

$\sqrt{a^{2} } - \sqrt{132}$

a = 11.489

round to the nearest tenth:

11.489 = 11.5
