Hi there!
We know that RST is an equilateral(all 3 sides the same length) triangle, and is therefore equiangular(all 3 angles the same value). Therefore, angle S and is equal to one-third of the triangle's angle measure.
180/3=60
60=7x+4
56=7x
x=8

Answer:
20%
Step-by-step explanation:
First, find the difference between $130 and $104. This equals $26, and to find this discount written as a percent, divide $26 by the original cost of the camera. 26/130=0.2, which represents a 20% discount.
Hey! Thanks for using Brainly.
Could you add a attachment or the question so we can know the two notes in the question? Once you do that I can assist you further.
Looking forward to hear your response.

Answer:
Option A.
Step-by-step explanation:
The given equation is
Liliana wants to write an equivalent expression.
It can be written as
Using commutative property, we get
![[\because A+B=B+A]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2BB%3DB%2BA%5D)
Using associative property, we get
![[\because A+(B+C)=(A+B)+C]](https://tex.z-dn.net/?f=%5B%5Cbecause%20A%2B%28B%2BC%29%3D%28A%2BB%29%2BC%5D)
Using distributive property, we get
![[\because An+Bn=(A+B)n]](https://tex.z-dn.net/?f=%5B%5Cbecause%20An%2BBn%3D%28A%2BB%29n%5D)
Using addition property, we get
Therefore, the correct option is A.
