B has the pair that are vertical angles
using the conversion factor the speed of the car is 44.74 miles/hr
From what i can tell, it would have Three Lines of Reflectional Symmetry due to its three vertices
The value of the angle θ is 160.52° then the value of the cosine will be negative 0.9428.
<h3>What is trigonometry?</h3>
Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
Angle θ is in standard position.
If sin(θ) = − 1/3 , and π < θ < 3π/2
Then the angle will be

Then add 180 degrees, then we have

Then the value of the cosine will be
