Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:


x+2x+21=180

Combine like terms:


3x+21=180

Subtract 21 from both sides:


3x=159

Divide both sides by 3:


x=53

Therefore, the value of x is 53 degrees.
