Answer:
120
Step-by-step explanation:
add 50+10=60
then 180-60=120
I hope this helps you
x= 180° - (103°+33°)
x= 180° - 136°
x= 44°
7/10 or 70% or 0.7
4 black, 10 red
10+4=14
now you put it over the total marbles
14/20=7/10
i don't know how your teacher wants you to give the answer but it is 7/10 or 0.7 or 70%
