You are asked for an angle. You need to use the inverse sine.

The answer is about 30 degrees. See below.

Step-by-step explanation:

Sin(y) = opposite / hypotenuse

opposite = 9cm

hypotenuse = 17 cm

Sin(y) = 9/17

y = sin-1(9/17)

y = sin-1(31.97) degrees.

To the nearest 1/10 of a degree, it would be

y = 32.0 degrees.

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)
