If a figure has been dilated by a scale factor of one third, which transformation could be used to prove the figures are similar using the aa similarity postulate?

a translation because it can map one angle onto another since dilations preserve angle measures of triangles.
a rotation because it can change the orientation of a figure since dilations do not preserve orientation.
a dilation because it can map one side onto another since dilations preserve side length of triangles.
a reflection because it can change the orientation of a figure since dilations do not preserve orientation.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

happy to

pls mark as brainliest

a is the right answer

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
