Answer:

answer shown below

Step-by-step explanation:

m of angle 1= 47⁰

m of angle 2= 137⁰

m if angle 3= 31⁰

find measure 1 by adding 90⁰+42⁰=133⁰ and subtract 180 from it to find 1

find measure 2 by subtracting 43 from 180

find measure 3 by adding measure 2 (137⁰) and 12⁰ together to get 138⁰ and subtract 180 to get 31⁰

hope this helps
