Answer:
: c2 = a2 + b2 - 2ab cos C
c²=20²+15²-2×15×20×cos50
c²=400+225-600×0.64
c²=241
c=√241=15.5ft
Answer:
On E2020 the answer is C
Step-by-step explanation:
They have the same y-intercept.
Answer:
y=-1/2x+2
Step-by-step explanation:
slope is -1/2 beware this is a negitive slope so it goes down like this \
go one up and go to the left 2 times and connect the dots
Sorry that is not a linear model. There is not a constant rate of change. Are you sure you copied it correctly
You have to set it up as two problems then combined like terms then add them together
