Answer:
Here's what I get
Step-by-step explanation:
I plotted the triangles in the diagram below.
Part A
The scale factor for dilation is ½, because every coordinate has been halved.
P (8, 0) ⟶ P' (4, 0)
Q (6, 2) ⟶ Q' (3, 1)
R (-2, -4) ⟶ R' (-1, -2)
Part B
When you reflect a point (x, y) about the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign. Thus,
P' (4,0) ⟶ P" (-4,0)
Q' (3,-1) ⟶ Q" (-3,-1)
R' (-1,-2) ⟶ R" (1,-2)
∆P"Q"R" has coordinates P" (-4,0), Q" (-3,-1), R"(1,-2).
Part C
∆PQR and ∆ P"Q"R" are not congruent, because corresponding sides are not equal.
Answer:
To simplify the following expression: 6 / (7+3i), we're going to multiply and divide the entire expression by (7+3i), as follows:
Now, the denominator has NO imaginary numbers.
Answer:
x=20
Step-by-step explanation:
45= measure of angle 6 (vertical angles)
45+ 5x+35 = 180 (Supplementary angles)
x=20
The correct answer is C. neither congruent nor similar.
Given that △ABC is transformed to △A'B'C' such that AB = A'B'.
We know that:
For triangles to be similar, all three angles must be same(AAA property) or all three sides must be in same proportion(SSS property) or two sides must be in same proportion and the included angle should be equal(SAS property).
For triangles to be congruent, all the three sides and all the three angles ,ust be exactly same.
Since △ABC and △A'B'C' have only one side equal, they are neither congruent nor similar.
