Triangle angle sum theorem
what is the value of s?

The triangle angle sum theorem states that the sum of all angles of triangle is equal to 180°. So, According to the theorem

Solve for s ~

Now, With the help of this value we can find the value of all angles

Sum of the interior angles of any triangles equalls to 180 degrees thus :

Collect like terms :

Subtract both sides 36

Divide both sides by 6

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)
