Answer:
alternate exterior angles m∠A =70 °
m∠B =80 °
m∠C =30 °
Step-by-step explanation:
1750mg in 1.75g just move the decimal place over three places.
so its 1750mg
The price of album y is $5.80. I solved the system of equations of B and C. Getting rid of the variable z, I was able to get rid of x next. Solving this system gave me $5.80 without having to substitute into the other equation.

The tangential line at a certain point is just the derivative so.

. At the point (1,6) we plug the x value in and get the slope at the point (y ' = 2)
The tangential line at that point is
y - 6 = 2(x - 1) (this is the answer)
