Answer:
other parallel side is 23m
Step-by-step explanation:
Let's assume other parallel sides as 'x'
One of the parallel sides of the trapezium plot measure 18m
so, y=18
distance between the two parallel sides measure 20m
so, h=20
now, we can use area of trapezium formula

now, we can plug values

we can set A=410
and then we can solve for x




"<span>all real numbers between 3 and 10 inclusive" could not be the answer, because these are x-values (values of the independent variable).
"</span><span>all real numbers between 19 and 54 inclusive" is the range. Why? Because in year 3, f(3) = height of tree = 5(3) + 4 = 19 feet.
In year 10, f(10) = 5(10) + 4 = 54 feet. </span>
Answer:
40, 60 and 80 degrees.
Step-by-step explanation:
Let the smallest angle be x degrees. Then:
The 3 angles are x, x + 40 and x + 20.
As there are 180 degrees in a triangle:
x + x + 40 + x + 20 = 180
3x = 180 -40--20 = 120
x = 40 degrees.
The other 2 angles are 60 and 80 degrees.
