I got 30, I’m not sure if it’s correct or not.
Answer: 53
Step-by-step explanation:
They are both right legs. Use a^2+b^2=c^2.
A= 28^2 B=45^2
A= 784 B= 2025. 2025+ 784= 2809 (radical 2809) To simplified is 53
If the number is x, then 3 times x -20 >10 and 3x-20>10. Adding 20 to both sides, we get 3x >30 and by dividing by 3 we get x >10
