Answer:
3/4 feet are eroding per year
Step-by-step explanation:
There are 12 months in a year. You know that every 4 months, the shoreline erodes 1/4 feet.
Divide 12/4 to get 3.
That means that the shoreline erodes 1/4 feet 3 times per year.
Multiply 3 by 1/4 to get an answer of 3/4.
Hope this helps :)

Answer:
A. 110
Step-by-step explanation:
Angles 4 and 6 are supplementary so if we add them together they will equal 180.
(5a + 10)° + (3a + 10)° = 180°
Simplify a bit to get 8a + 20 = 180
and 8a = 160.
a = 20. Now sub that value of a into the expression for angle 4:
5a + 10 --> 5(20) + 10 = 110°
