How do I simplify? I forgot, it's been a little.

Below

Step-by-step explanation:

You simplify by adding the common factors together, like 3x+4x, which gets 7x. Also the same for subtraction, multiplication, and division.

Simplify it by dividing both the numerator and denominator by the same amount. They both must have a result.

For example, we have 8/16.

We can divide it by 2 which gives us 4/8, but it can be simplified more.

We can divide it by 4 this time, which gives us 2/4, but it can still be smaller.

We can divide it by 8 this time, which gives is 1/2. This is the farthest simplification that you can get for 8/16.

Hope this helps

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
