Answer:

41.4

Step-by-step explanation:

The Law of Cosines tells you ...

a² = b² +c² -2bc·cos(A)

where sides a, b, c are opposite angles A, B, C, respectively. Filling in the given numbers, you have ...

a² = 30² +26² -2·30·26·cos(95°)

a² ≈ 1711.96

a ≈ √1711.96 ≈ 41.38

The length of BC is about 41.4 units.
