Answer:

a) 2

b) left: 3; lower right: 5

c) upper right: 53°; bottom: 82°

Step-by-step explanation:

a) The top side of polygon B is 5 units; the corresponding top side of polygon A is 2.5 units, so the dimensions of polygon A are multiplied by the scale factor 5/2.5 = 2 to give the dimensions of polygon B.

the scale factor is 2

b) Sides of polygon B are 2 times the length of the corresponding side of polygon A.

left side: 2×1.5 = 3

lower right side: 2×2.5 = 5

c) Corresponding angles of similar figures are congruent.

upper right angle: 53°

bottom angle: 82°

Nookie1986 [14]

$\text{Slope}=\frac{-1--6}{3-5}=\frac{5}{-2}$ $\begin{gathered} y-y_1=\frac{5}{-2}(x-x_1) \\ \\ y--6=\frac{5}{-2}(x-5) \\ \\ -2(y+6)=5(x-5) \\ -2y-12=5x-25 \\ 5x+2y=25-12 \\ 5x+2y=13 \end{gathered}$

The missing values are (-6, -9) ( The last option)

Explanation:

x= - 6 has already produced the value of y as 5, the only pair in the given option the make the given ordered pairs NOT to be a function is (-6, -9) since it will give the value of y to be - 9.
