Answer:
Step-by-step explanation:
According to the given data:
A particular beach is eroding at a rate of 4 centimeters per year. A realtor converts this rate to millimeters per day
10 mm = 1 cm
Now convert 4 cm into mm
4 cm= 4*10 mm
4 cm= 40 mm
There are 3365 days in 1 year
Rate to millimeters per day = 40 mm in 365 days
= 40/365 mm per day
= 8/73 mm per day
Divide the term.. We get,
= 0.109589 mm per day .
b
The sum of angles in a triangle is 180°. Therefore,
x - 11 + 48 + 90 = 180
x + 127 = 180
x = 53°
answer will be 2÷18=9
and the answer is 9
