Which sequence of transformations would result in a figure that is similar, but not congruent, to the original figure?

select all that apply.

a. a dilation with a scale factor of 1.9 followed by a rotation of –30°
b. a dilation with a scale factor of 0.1 followed by a translation of 5 units left
c. a reflection across the y-axis followed by a dilation with a scale factor of 10
d. a rotation about the origin of 65° followed by a reflection across the x-axis

The correct answers are:

A.a dilation with a scale factor of 1.9 followed by a rotation of –30° ; B.a dilation with a scale factor of 0.1 followed by a translation of 5 units left ; and C.a reflection across the y-axis followed by a dilation with a scale factor of 10

Explanation:

A dilation shrinks or stretches a figure.  This means it creates a figure that is similar to, but not congruent to, the original figure.  All of the figures with dilations will be similar but not congruent to the original figure.

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

the answer is 62.8 cubic units
