Answer:
The correct answer is A. A triangle has side lengths of 5, 10, and 5√3.
Step-by-step explanation:
Let's recall that a property of the right triangles 30 - 60 - 90 is that the lengths of the sides of this type of triangles are in the ratio 1 : 2: √3.
Thus, if the short leg is 5 units, the length of the other leg is 5 √3 and the length of the hypotenuse is 10 units.
The correct answer is A. A triangle has side lengths of 5, 10, and 5√3.
