Question 9 answer is 80 and for 10 it is 72 and for 11 it is 112 and for 12 it is 143
Answer:
a = 139.1
b = 56.2
Step-by-step explanation:
A. Reference angle = 68°
Opp = a
Hyp = 150
Therefore:
Sin 68 = opp/hyp
Sin 68 = a/150
150*sin 68 = a
a = 139.1 (nearest tenth)
B. Reference angle = 68°
Adj = b
Hyp = 150
Therefore:
Cos 68 = adj/hyp
Cos 68 = b/150
150*cos 68 = b
b = 56.2 (nearest tenth)
4 multiplied by x to the power of five
Answer:
240
Step-by-step explanation:
ok, so first you look closely at the problem. convert pounds to ounces, since you dont have enough to do it the other way. so if 1 pound is 16 ounces, 3 pounds is 48. he has 48 ounces. if 10 ounces makes 60, 40 ounces makes 240. now you have 8 left. now im not sure about this part, but if you took the 8 left over, and if 10 ounces makes 60, 8 ounces makes 48 more.
