Answer:
your answer is 65 for the two missing angles
you take 50 and subtract it from 180 to get 130 then divide that by 2 you get 65
Step-by-step explanation:
or you can use the line which also equals 180 in all it has 115 on it so u would subtract 50 from it to get one of the angles then u would add 65 and 50 to get 115 and subtract 115 from 180 to get 65
