Answer:
f
Step-by-step explanation:
5.105421147
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
The answer is √ 6
2 2/5
4 x 3/5
12/5 = 2 2/5
