Pls me pass this class y’all which angle of rotation is determined by the matrix below? (pictured above) a. 30 degrees b. 60 degrees c. 120 degrees d. 300 degrees u : ))

angle of rotation will be 60°

Step-by-step explanation:

The given matrix is

And we have to find the angle of rotation.

Since matrix showing angle of rotation θ  is denoted by

Matrix for angle of rotation will be

Therefore, angle of rotation will be 60°

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
