Answer:
Step-by-step explanation:
<A = <C (given)
DB = EB (given)
<B = <B cuz its in both the triangles (forgot the sentence to prove it)
proved using AAS
hope this helped
D because it says you will be getting at least 4500 or more dollars by adding the adult and student tickets

Answer:
see the explanation
Step-by-step explanation:
we have triangle ΔABC
step 1
Rotate 90 degrees clockwise ΔABC about point C to obtain ΔA'B'C'
Remember that
A rotation is a rigid transformation
An object and its rotation are the same shape and size, but the figures may be turned in different directions
so
ΔABC and ΔA'B'C' are congruent
ΔABC≅ ΔA'B'C
step 2
Dilate the triangle ΔA'B'C' to obtain triangle ΔEDF
Remember that
A dilation is a non rigid transformation
A dilation produces similar figures
If two figures are similar, then the ratio of its corresponding angles is proportional and its corresponding angles are congruent
Find the scale factor of the dilation
The scale factor is equal to the ratio of corresponding sides
In this problem
Let
z ----> the scale factor
so

Multiply the length sides of triangle ΔA'B'C' by the scale factor z to obtain the length sides of triangle ΔEDF
Note: in this problem the scale factor z is less than 1
That means ----> the dilation is a reduction
Line BCE is supplementary, which means its straight or it is 180 degrees. so you take the angle of BCF, which is 63, and subtract that from 180 to get 117, so the measure of angle FCE is 117 degrees <span />
