HELPPP!!!Kelsey uses the similarity statement to describe the triangles below.
Ganezh [65]

RT = 8 , RS = 3 AND ST = 5.4


RV = 4 , RU = 1.5 AND UV = 2.7


∴ RT/RV = 8/4 = 2


AND RS/RU = 3/1.5 = 2


AND ST/UV = 5.4/2.7 = 2


∴Δ RTS IS SIMILAR TO ΔRVU


SO, the best statement is:


Each pair of sides corresponds with a common ratio of 2.

Here is rectangle A. Block A. Rectangle B is ¹/₅ longer than A Block B. Rectangle C is ¹/₃ longer than B Block C. The total leng
Hoochie [10]

Answer:

Rectangle C is 14 cm longer than B

Step-by-step explanation:

Let  x be the length of Rectangle A. Rectangle B is ¹/₅ longer than A Block B,

Therefore the length of rectangle B is:

x+\frac{1}{5}x

Rectangle C is ¹/₃ longer than B, therefore the length of rectangle c is:

x+\frac{1}{5}x+\frac{1}{3}(x+\frac{1}{5}x) =x+ \frac{1}{5}x+\frac{1}{3}x+\frac{1}{15}x=x+\frac{9}{15}x

The total length of all three rectangles is 133 cm.

Length of rectangle A + Length of rectangle B + Length of rectangle C = 133 cm

x+x+\frac{1}{5}x +x+\frac{9}{15}x=133\\x+x+x+\frac{1}{5}x +\frac{9}{15}x=133\\3x+\frac{12}{15}x=133\\ 45x+12x=1995\\57x=1995\\x=35cm

Therefore the length of rectangle A is 35 cm, the length of rectangle B is 35+\frac{1}{5}*35=42\ cm and the length of rectangle C is 35+\frac{9}{15}*35=56\ cm

Rectangle C is ¹/₃ longer than B, which is 14 cm (42\3) longer than B
