the measures of an exterior angle and the adjacent interior angle add p to 360 because they form a linear plane?
inn [45]
Sadly, I can't see the picture you're looking at as you make that statement.
But I'm pretty sure that when you combine an exterior angle with the interior
angle adjacent to it, you'll wind up with 180°, because they form a linear line.
There actually isn't any such thing as a linear plane.

A truck can be rented from Company A for ​$80 a day plus ​$0.30 per mile. Company B charges ​$20 a day plus ​$0.50 per mile to r
mylen [45]

Write equations for both companies:

Company A = 80 + 0.30x

Company B = 20 + 0.50x

X = number of miles.

Set the equations to equal and solve for x:


80 + 0.30x = 20 + 0.50x

Subtract 0.30x from both sides:

80 = 20 + 0.20x

Subtract 20 from both sides:

60 = 0.20x

Divide both sides by 0.20:

x = 60 / 0.20

x = 300


The answer is 300 miles.
