Final answer:
In a 30-60-90 triangle, the ratio between the lengths of the two legs is 1:√3.
Step-by-step explanation:
In a 30-60-90 triangle, the ratio between the lengths of the two legs is 1:√3. Option 1 is correct.
To understand this, let's assume the length of the shorter leg is 1 unit. Then, using the properties of a 30-60-90 triangle, the length of the longer leg would be √3 units.
Therefore, the correct ratio is 1:√3.
