Answer:
Step-by-step explanation:
We would apply the law of Cosines which is expressed as
a² = b² + c² - 2abCosA
Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Therefore
BC² = 26² + 30² - 2(26 × 30)Cos95
BC² = 676 + 900 - 2(780)Cos95
BC² = 1576 - 1560Cos95
BC² = 1576 - 1560 × - 0.087
BC² = 1576 + 135.72
BC² = 1711.72
BC = √1711.72
BC = 41.4 to the nearest tenth
