Answer:
14
Step-by-step explanation:
Let us denote the longest side as "y"
✓According to trigonometry, Largest side and largest angle are always opposite while the shortest side and shortest angle are opposite.
✓ the length vof shortest sides=11
Then
Sin(50)/11 = sin(70)/ y
Cross multiply
Sin(59) × y = 11 × sin(70)
y= [11 × sin(70) ] / sin(50)
y= (11×0.9397)/0.7660
y=13.493
Hence, he length of the longest side rounded to the nearest tenth is 14
