Explanation

Polymerization is the chemical process where small molecules (monomers) join to form large chains (polymers), which make up plastics.

Petroleum-derived hydrocarbons are used in this process to create various plastic materials like polyethylene and polypropylene.

Explanation

Let's denote the three angles as x, x, and 2x, since they are in the ratio 1:1:2.

The sum of the angles in a triangle is always 180°:

x + x + 2x = 180°

Combine like terms:

4x = 180°

Divide by 4:

x = 45°

Now that we know x, we can find the other angles:

x = 45°

x = 45°

2x = 90°
