Answer:
3) answer is 120 4) 105
Step-by-step explanation
3) 180 - (70+50) = 60
180-60 = 120 <-- thats the answer
4) 180 - ( 80+25) = 75
180 - 75 = 105 < thats the answer
We cannot say with certainty how many times Rodney will get orange.
Assuming that the packs are constantly replaced:
Orange constitutes 2/6, or 1/3, of a pack.
2/6 x 30 = 60/6 = 10 orange juice packs.
Answer:
Let us make the last unknown interior angle be "b"
b+a+36=180
b=180-36-a
b=144-a
for the main triangle,
a+144-a+a-28=180
2a+116=180
2a=180-116
2a=64
a=32
so a=32
