2=137

3=31

1=47

Step-by-step explanation: I took test

Answer 2

2=137⁰

3=31⁰

1=47⁰

Explanation:

2 is on a straight line with 43 and a straight line is 180 degrees so 180-43=137

A triangle has 180 degrees and we figured out 2 so 137+12 then subtract from 180 equals 31 degrees

3. The box in the triangle represents 90⁰ so 43 + 90 then subtract from 180 equals 47
