Answer 1

`t = 17.3`

Explanation:

Given ∆TUV,

m < T = 87°

TV = u = 11

TU = v = 14

UV = t = ?

Find t using the Law of Cosines.

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

Plug in your values.

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

`t^2 = 317 - 16.119`

`t^2 = 300.881`

`t = √(300.881)`

`t = 17.3` (to the nearest tenth)
