Respuesta :
x + 150 = 180
x = 180 - 150
x= 30
then
X = 30
so, when x+ 85 =180
30+85 = 180
115= 180
180-115
= 65
Answer:
65 degrees
Step-by-step explanation:
Make a triangle with x as one of the degrees. So 180 - 150 = 30 would be another, and 85 would be the other. A triangle's degrees is 180, so 85 + 30 = 115, and 180 - 115 = 65, and that would be the answer.
