Explain the reason why when you find one angle you can find the remaining angles.

if you find two angles of a triangle you can find the remaining angle because they all add up to 180 degrees, so you can add the two angles together and the difference between 180 and the sum of the two angles is the measurement of the missing angle. Hope this helped :)

Explanation:

Explanation:

The opposite angle is the same as the known angle. Each of the adjacent angles is the supplementary angle to the known angle. That is the pair add up to 180 degrees

d. new methods of assembly are introduced.

explanation:

this allows for the goods to be made on a larger scale. not faster because now it is shown to be made better, hence the greater productivity in the question. it is calling for something new to be introduced.
