Answer: The first answer in the screenshot is correct. Sides 5, 10 and 5√3
Step-by-step explanation: In a 30°60°-90° triangle, the side opposite the 30° angle (shortest side) is half the length of the hypotenuse. So you have to choose one with 5 & 10. Use the Pythagorean theorem to calculate the remaining side a² + b² = c²
5² + b² = 10², so b² = 100-25 √b²=√75 so √(25)(3)
b= 5√3
