Answer:
<em>B</em>
Step-by-step explanation:
<u>Dilations</u>
Given a point A(x,y) and a scale factor k the dilated image of A, called A' is calculated as A'=(kx,ky), assuming the same scale factor is applied in both axes.
The pentagon ABCDE was dilated to create pentagon A'B'C'D'E'. To find the dilaton rule used, we must find two clear points where the coordinates of both axes can be easily read from the graph.
Point C(-2,0) maps to C'(-5,0). This gives us the scale factor for the x-axis of -5/(-2)= 5/2.
The y-coordinate of E is 2 and the y-coordinate of E' is 5. This gives us the same scale factor for the y-axis of 5/2.
Thus, the rule to dilate the pentagon is:
B
It’s D because if it’s parallel then it’s gonna be negative
Answer:
95"
Step-by-step explanation:
Cos55° = 0.573576436351 ≈ 0.6
X = Height of building
Cos55° = 57" ÷ X
X= 57" ÷ 0.6
X= 95"
I hope this helps! :)
Answer:
AAS Congruence Theorem
Step-by-step explanation:
I see 2 angles of one triangle shown to be congruent to 2 angles of the other triangle. After the two angles, there is a side in common to both triangles which is congruent to itself. That makes angle-angle-side.
