Solve 5+7√x+6=26 for x.

225/49

Step-by-step explanation:

5+7√x+6=26

7√x+11=26

Step 1: Add -11 to both sides.

7√x+11+−11=26+−11

7√x=15

Step 2: Divide both sides by 7.

7√x

x=225/49

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
