Hey there! I'm happy to help!
Let's set this up as a proportion (2 equal ratios).

If you multiply the diagonal numbers, their products will be equal. (412×g=103×184). This is called cross multiplying. Now we can solve for g.
412g=18952
Divide both sides by 412.
g=46
Therefore, the boat will need 46 gallons of gasoline to go 184 miles.
Have a wonderful day! :D
Alternating Angles?
If so, its the same, so still 45.19
If its not Alternating Angles, then I’m lost.
Or is T referring to the line?
Answer:
520
Step-by-step explanation:
To know what value should be placed in the box, let us calculate the carry out the operation.
Please see attached photo for explanation.
From the calculations made as shown in the attached photo, the value that should be placed in the box is 520
We must set the two expressions to be equal:
216t + 18 = 362t + 8
Subtract 216t from both sides:
18 = 146t + 8
Subtract 8 from both sides:
10=146t
Divide both sides by 146:
t = 10/146 = 5/73
