Answer:Fee as a function of miles:
f(m) = 16.95 + 0.92m
140.23 = 16.95 + 0.92m
0.92m = 140.23 - 16.95
0.92m = 123.28
m = 123.28/0.92
m = 134 miles
Step-by-step explanation:
Answer:


Step-by-step explanation:
It is important to remember that, by definition, the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
In this case we can idenfity that the angle
is an exterior angle of the triangle QRT. Then:

Where:

Substituting values and solving for "x", we get:

Then:

The sum of the interior angles of a triangle is 180°, therefore:

Solving for
, we get:

200+15x=320
and then the actual answer to the question is 8 lawns.
