Answer 1

`t = 17.3`

Explanation:

Given:

∆TUV,

m < T = 87°

VT = u = 11

TU = v = 14

VU = t = ?

Use the Law of Cosines to find t as shown below:

`t^2 = u^2 + v^2 - 2uv*cos(T)`

`t^2 = 11^2 + 14^2 - 2*11*14*cos(87)`

`t^2 = 121 + 196 - 308*0.0523`

`t^2 = 317 - 16.1084`

`t^2 = 300.89`

`t = 17.3` (rounded to the nearest tenth)
