Question

Please help me need help ASAP don’t know how to solve

Answer 1

Using the triangle similarity postulates, you can verify that

$\cfrac{12}{y}=\cfrac{y}{4}\\ \\ \Rightarrow y^2=48\\ \\ \Rightarrow y=\sqrt{48}=4\sqrt{3}$

Answer 2

Answer: The answer is A. 4 √3.

Step-by-step explanation: You may use the triangle similarity postulate and can verified that: $\frac{12}{y}=\frac{y}{4}$, $y^{2}=\sqrt{48}$, and $y=\sqrt{48}=4\sqrt{3}$. I hoped this is very helpful, please mark me as brainliest, and have a happy holidays!!! :D
