From the circle geometry theorem, a tangent to a circle makes 90° angles with the radius of the circle.
RQ is perpendicular to QP
Triangle RQP is a right-angled triangle
by Pythagoras theorem

Answer:
the desired line is y = (1/2)x + 1
Step-by-step explanation:
Write these two points as (0, 1) and (-2, 0).
Now, as we go from (-2, 0) to (0, 1), x increases by 2 and y increases by 1. Thus, the slope, m, of the desired line is m = rise / run = 1 / 2.
Then the desired line is y = (1/2)x + 1 (since b is already given as (0, 1) )
<span>1 gallon = 231 in
1 inch = 2.54 cm
</span><span>Honestly, I would say it will fill up because if your solving for the amount of centimeters in a gallon then the gallon would fill up. It just makes sense to me, don't know if it's correct because what I did was take the amount of centimeters in a inch and multiply it by the total amount of inches in a gallon.

HOPE THIS HELPS! ^_^
