Answer:
The answer is y = 3(4)^x or answer choice C
Answer:
12.9
Step-by-step explanation:
cos 72 = 4/x
x = 4/cos72
x = 12.9
Answer:
79
Step-by-step explanation:
79 should be the correct amswer
True , because all properties preserved under dilation from triangle ABC to A'B'C'.
<h3>What is dilation?</h3>
Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.
Given : A triangle ABC is dilated by a factor of 2/3 , result triangle A'B'C'
To find :After dilation, properties of triangle ABC and A'B'C' is true or false.
Dilation of a triangle are result either decrease or increase the corresponding length of triangle , its depends on by which scale factor triangle is dilated ,and dilation does not affect the angle measures of triangle.here scale factor is 2/3 so corresponding sides of triangle A'B'C'' decreases.
So, dilation of triangle are not congruent but similar to the original triangle ABC
Therefore , basic properties of triangle preserved under dilation of triangle by a scale factor.
