Please wright about both and quick this is for a test

When you add both <1 and <2 together they should equal <4, I know this because if you cut out both <1 and <2 and put them on <4 they would be equal. Also all three angles of a triangle 180, I know this because if you cut out all three angles and put them right beside each other they will make a line and that line equals 180.

Hope this helps

see below

Step-by-step explanation:

1. the sum of all angles inside a triangle is always equal to 180.

2.  its an alternate angle in a parallel lines,  ∠3 is congruent ∠2  (∠3≅∠2)

what is the original number? you forgot to add it.
