What is the length of side s of the square shown below?

Answer:
5.105421147
Step-by-step explanation:
since this triangle has two 45 degree angles, either works for the sine ratio
so sin 45 = s/6 and sin 45 = 0.85090352453
then 0.85090352453 = s/6 now multiply both sides by 6
0.85090352453 times 6 = s
so s = 5.105421147
