Triangles = 180 so you’d use the equation ABC (60) + BAC (50) + ACB (x) = 180
Which equals out to ACB= 79
Answer:
96°
Step-by-step explanation:
Answer:
the annual rate of inflation r is 0.023
Step-by-step explanation:
Given by the expression:

The average price of a gallon of milk increased from $0.36 in 1913 to $3.53 in 2013.
Let 

n = 2013 - 1913 = 100
replacing our values into the given equation; then the annual rate of inflation r is as follows:

r = 0.023
Hence, the annual rate of inflation r is 0.023
You can simply expand each product and see whether it gives you a difference of squares.
