Question

What is the answer????

Answer 1

Let's see

• (10y)²=(6y)²+64²
• 100y²-36y²=(64)²
• 64y²=64²
• y²=64
• y=√64
• y=8

Answer 2

y = 8

Explanation:

A 3-4-5 right triangle, and its multiples, are the only ones with rational side lengths in the ratio 3:5. In other words, the 6y : 10y side ratios mean that ...

3 : 4 : 5 = 6y : 64 : 10y

or

64 = 8y

y = 8 . . . . . . . divide by 8
