I need answered asap please! Explain what dilations and scale factors would be considered similarity transformations.

1 answer:

4 0

Similarity. ... In general, similarity transformations preserve angles. Side lengths are enlarged or reduced according to the scale factor of the dilation. This means that similar figures will have corresponding angles that are the same measure and corresponding sides that are proportional. Hope it helps!

Use the image below to answer the following question. Find the value of sin x® and cos yº What relationship do the ratios of sin

Flauer [41]

Answer:

sin(x) and cos(y) are equal and have ratio of 1 : 1

First find the missing hypotenuse using Pythagoras theorem:

a² + b² = c²

12² + 5² = c²

c = √144+25

c = 13

using sine rule:

$sin(x) = \dfrac{opposite}{hypotenuse}$

$sin(x) = \dfrac{5}{13}$

using cosine rule:

$cos(y) = \dfrac{adjacent}{hypotenuse}$

$cos(y) = \dfrac{5}{13}$

fomenos

Answer:

Step-by-step explanation:

4^2 +5*3^2 -4^2 / 2^3

order of operations says to do first parenthesis, exponents, then division and multiplication

first the exponents

4^2 = 16

3^2= 9

4^2=16

2^3=8

16+ 5*9-16/8

then multiply 5*9

=16+ 45 -16/8

simplify the fraction

=16+ 45 -2

add them

=59

i hope this helps
