F(m)=20+0.05m
f(m)=cost(c)
20=initial cost and will be the y-intercept
0.05=the cost per mile and will be the slope
m=the number of miles driven

Angle 2 is 110 degrees. Allen claims that we do not have enough information to solve for angle 1. Is he correct? Why or why not?
devlian [24]

Allen's claim that we do not have enough information to solve for angle 1 is incorrect

<h3>How to calculate the measure of angle 1</h3>

Given that:

Angle 2 = 110 degrees

Angle 1 and angle 2, are the only angles on the straight line.

So, we have:

\angle 1 + \angle 2 = 180

Substitute 110 for angle 2

\angle 1 + 110 = 180

Subtract 110 from both sides

\angle 1 = 70

The measure of angle 1 is 70 degrees.

So, we can conclude that Allen's claim is incorrect
