Question

find the missing side of each triangle. love your answers in simplest radical form.

Answer 1

Using pythagorean theorem

$\\ \sf\longmapsto x^2=11^2+11^2$

$\\ \sf\longmapsto x^2=121+121$

$\\ \sf\longmapsto x^2=242$

$\\ \sf\longmapsto x=\sqrt{242}$

$\\ \sf\longmapsto x=15.4$

Answer 2

Step-by-step explanation:

Use the pythagorean theorem

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

$11 {}^{2} + 11 {}^{2} = c {}^{2}$

$121 + 121 = c {}^{2}$

$c = \sqrt{242} = 2 \sqrt{11}$
