Option B: 48/73 is the right answer
Step-by-step explanation:
Given triangle is a right-angled triangle which can be solved by using trigonometric ratios
When using the trigonometric ratios, the side opposite to the angle under consideration will be perpendicular and the other side will be base
so,
In the give triangle,
For ∠U
Perpendicular = P = 55
Base = B = 48
Hypotenuse = H = 73
The trigonometric ratio for cosine is given by:
[tex]cos\ U = \frac{B}{H}\\cos\ U = \frac{48}{73}[/tex]
Hence,
Option B: 48/73 is the right answer
