Answer: The scale factor of the dilation is 1/3.
In a dilation, we are multiplying all the points by a constant to get a set of new points. The shapes will be similar.
In this case, we are moving from Point P at (-6, 6) to Point P' at (-2, 3).
So how does the point change. Let's write and solve the following equations.
-6k = -2 or 6k = 2
k = 1/3 k = 1/3
In both cases, the point was multiplied by 1/3. This is true of all the points.
Answer:
m ∠ W is 58.2°
Step-by-step explanation:
Given:
XY = 15
WZ = 22
∠ XZY =25°
To Find:
m ∠ W = ?
Solution:
In right angle triangle Δ XZY, by Sine identity we have
∴ XZ = 35.49
Now in right angle triangle Δ WZX, by tangent identity we have
∴m ∠W =58.2°
