now, notice, the ratio is from small to large, so the larger right-triangle sides are 5 times larger than the small one then.
now, recall, a right-triangle with a hypotenuse of 5, will be a 3,4,5 triangle, you can check using the pythagorean theorem, thus, check the picture below.
Answer:
D
Step-by-step explanation:
if a<b,then b<a is the answer
82 + 79 + 72 + 72 + 81 + 77 + 69= 532
532/7 = 76
The mean is 76
