Solution
let p be the perimeter of the triangle then
3p=75-2p   collect the like terms
3p+2p=75
5p=75  divide both side by 5
5p/5=75/5⇒p=15.
therefore the perimeter of triangle is 15 units

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.
