Answer: 30 couples.
Justification:
You can follow a systematic approach to tackle this kind of problems.
Construct a chain of ratios whose units cancel out to yield to a result with the right units of the answer you are looking for.
In this case you want to know the number of couples that took the ride in 30 minutes.
The input data are:
1 couple / seat
1 seat / minute
Then, by multiplying those two data you get: [1 couple / seat] * [1 seat / minute], which, treating the units appropiately yields to 1 couple / minute.
Next, you realize that when you muliply 1 couple / minute times the number of minutes you get the number of couples that took the ride in that time.
So, the answer is: 1 couple / minute * 30 minute = 30 couples (the minutes cancel out because they appear in the denominator and numerator).
So, when you work with ratios and proportions, the use of units helps you a lot to figure out the way to get the answer.

Answer:
The two leg sides
Step-by-step explanation:
The two congruent sides of an isosceles triangle are the leg sides, while the base will be "x √2" of the measurement of the congruent sides.
Remember, the rule for isosceles triangle sides is: 1, 1, √2.
