Since we know that squares have the same length on all sides, you would find the square root of 170
√170=13.03840481
rounded to the nearest tenth would be 13.1
You can check your work by multiplying 13.1 by 13.1 which equals 170.3
I try to explain the problem and give the answer, I hope this helps!
Answer:
Step-by-step explanation:
the first one
Consider a ABC right angled at C and
Then,
‣ Base [B] = BC
‣ Perpendicular [P] = AC
‣ Hypotenuse [H] = AB
Let,
Base = 7k and Perpendicular = 8k, where k is any positive integer
In ABC, H² = B² + P² by Pythagoras theorem
