Hello! I believe the answer to your question is C (hours). If t is the amount of time it takes, hours is a unit of time, therefore I assume that would be your answer. :)

For the blank on the left, the answer is "angle ABC" without quotes of course. This is because we're using the substitution property which is the reasoning for statement 4. To elaborate, we connect statement 1 and statement 3 to get to statement 4.
The last statement, statement 5, is simply a repeat of the claim we want to prove. So you'll just copy/paste where it says "prove" as your last statement. Always start with the "given" and end up with "prove" is how I think of it.
The reasoning for the last statement is "definition of congruence". If two angles are congruent, then they have the same angle measure.
Answer:
16.2 foot shadow
Step-by-step explanation:
Let the shadow cast by 27 foot tree be x.
Using ratio and proportions,
18 / 30 = x / 27
(18 x 27) / 30 = x
x = 486 / 30
x = 16.2
