Question

can yall help me?

Answer 1

The first part (angles 1 2 and 3) is straightforward. Since they’re all three angles inside a triangle, simply add them up and set them equal to 180. That’s your first equation.

For the second equation, notice how angles 3 and 4 are on a straight line. Therefore angles 3 and 4 add up to 180 as well.

Since angle 3 + angle 4 add up to 180, that means angle 3 = (180 - angle 4)

So you can go back to the first equation, substitute angle 3 = 180 - angle 4, to get another equation in terms of angles 1 2 and 4 only
