180 ÷ 3 = 60 (<em>RST</em>)

60  = 7x + 4 (<em>RT</em>)

56=7x (<em>S</em>)

\bf\boxed{{x=8}}

We see the 3 step method. In this case, we're NOT going to go all the way to a 360, because this is NOT a rectangle neither a square. So, we only go 180. Anyways, 360 by 2 = 180. it's almost the same concept.

So, like we said, the 3 step method. Plug in RTS and simplify by 180. Then, we brake it down from there.

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
