Answer:
A. <em>ΔJKL is not congruent to ΔJ'K'L' because the rules do not represent a sequence of rigid motions.</em>
Step-by-step explanation:
ΔJKL is mapped to ΔJ'K'L' using the rules 
followed by 
From geometry we know while rotating, reflecting and translating the size of the figure remains as it is, so they are congruent.
But in case of dilation the figure gets resized i.e their size gets changed. So they are similar not congruent.
In this case, first the triangle goes under i.e 2 units translated to right and 3 units translated to up.
But after then it undergoes , where it undergoes a dilation of factor 2, so it is no more congruent to the original figure.
Solution:
Given Expression is 1/40* x = 1/8
Step : Define x in the Equation:
Step : Divide the Equation by 8
Step : Do cross multiplication
Step : Arrange it in particular form
____________________________
☞ 1/40x = 1/8
☞ x/40 = 1/8
☞ x = ⅛ × 40
☞ x = 5
.
Therefore, Answer is 5.

Answer:
Y = acos( X ) returns the Inverse Cosine (cos-1) of the elements of X in radians. The function accepts both real and complex inputs. For real values of X in the interval [-1, 1], acos(X) returns values in the interval [0, π].
