a carpenter uses a circular saw to cut a piece of lumber at a 145 angle what is the measure of the other angle formed by the cut
Anettt [7]

The other angle would be 35 degrees. This is because in a straight line (the wood) there are 180 degrees and when you take away 145 (the cut) you are left with 35.

180-145= 35

I hope this helps!

How does the structure of a trinomial with a leading coefficient of 1 and a positive constant help to factor it?
mixer [17]

Answer:

See explanation

Step-by-step explanation:

If a quadratic trinomial has a leading coefficient of 1 and a positive constant, then it is very easy to factor.

You just have to look for two factors of the constant term that add up to the coefficient of x( the middle term).

Then you write as factors.

For instance;

{x}^{2}  +5 x + 6

To factors of 6 that add up to 5 are 2 and 3.

Therefore the factorization is:

(x + 2)(x + 3)
