Answer:
![\boxed{u = 13.7}](https://tex.z-dn.net/?f=%5Cboxed%7Bu%20%3D%2013.7%7D)
Step-by-step explanation:
Using cosine rule
![c^2 = a^2+b^2-2ab\ CosC](https://tex.z-dn.net/?f=c%5E2%20%3D%20a%5E2%2Bb%5E2-2ab%5C%20CosC)
Here c = u, a = 9 , b = 21 and C = 28
![u^2 = 9^2+21^2-2(9)(21)\ Cos 28\\u^2 = 81+441-(378)(0.88)\\u^2 = 522 - 333.75\\u^2 = 188.24](https://tex.z-dn.net/?f=u%5E2%20%3D%209%5E2%2B21%5E2-2%289%29%2821%29%5C%20Cos%2028%5C%5Cu%5E2%20%3D%2081%2B441-%28378%29%280.88%29%5C%5Cu%5E2%20%3D%20522%20-%20333.75%5C%5Cu%5E2%20%3D%20188.24)
Taking sqrt on both sides
u = 13.7
