It is 50 degrees.
Since you already know two are 90 and 40 add them together and you get 130.
A triangle has 180 degrees so minus 130 from that
180-130=50

Answer:
(- 2, - 4 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then
multiply each of the coordinates by
, thus
(- 6, - 12 ) → (
× - 6 ,
× - 12 ) → (- 2, - 4 )
this forms a right triangle where you need to calculate the length of the hypotenuse by using the Pythagorean theorem
a^ + b^2 = c^2
6^2 = 36
9^2 = 81
36+81 = 117
sqrt(117) = 10.816
