Me i’m stuck. will give brainliest!

Triangle SET is similar to triangle SAR, so corresponding sides have the same ratio. This means

... ST : SR = ET : AR = 8.19 : 6.37

Then ST : TR = 8.19 : (6.37+8.19) = 8.19 : 14.56

Using division symbols, this is

... ST/TR = 8.19/14.56

Multiplying by TR gives

... ST = TR×(8.19/14.56) = 20.8×8.19/14.56

... ST = 11.7

check the picture below.

so, therefore, the triangles are similar by AA.

now, notice the length RT = 20.8, thus whatever ST might be, RS picks up the slack from the 20.8, namely RS = 20.8 - ST. Then we can use proportions from the corresponding sides.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
