I believe #7 is c but i dont know the other one
4 dimes, 8 pennies or 1 quarter, 2 dimes, and 3 pennies
3 can go into 70 about... 23.3 times!
I hope I answered your question!:)
Do do this problem, you need to use the Law of Cosines!
You are trying to find length b, so
b^2 = a^2 + c^2 - 2ab cos B
b^2 = 22^2 + 28^2 - 2(22)(28) cos 34
b^2 = 484 + 784 - 1232 cos 34
b^2 = 1268 - 1232 cos 34
b^2 = 246.6257
b = 15.7 yards
Hope this helps!
