Respuesta :

Using cosine law, the value of x in the triangle is 54.7 units.

How to find the side of a triangle using cosine law?

c² = a² + b² - 2ab cos C

Therefore,

x² = 47² + 45² - 2 × 47 × 45 cos 73

x² = 2209 + 2025 - 1236.73231098

x² = 4234 - 1236.73231098

x² = 2997.27

x = √2997.27

x = 54.747328702

Therefore,

x = 54.7 units
