12^2 + 6^2 = x^2
144 + 36 = x^2
180 = x^2
13.416407865 = x
rounded
x = 13.4
10:14, 15:21, 20,28
All you need to do when finding equal ratios is multiply both sides by the same number, In this case you could multiply both sides by 2 and get 10:14 or multiply both sides by 10 and get 50:70. The concept is quite easy.
Hope this helps
Answer:
![\large\boxed{\sin C=\dfrac{5}{13}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Csin%20C%3D%5Cdfrac%7B5%7D%7B13%7D%7D)
Step-by-step explanation:
![sin=\dfrac{opposite}{hypotenuse}\to\sin C=\dfrac{AB}{AC}\\\\\text{We have}\ AB=25,\ AC=65.\ \text{Substitute:}\\\\\sin C=\dfrac{25}{65}=\dfrac{25:5}{65:5}=\dfrac{5}{13}](https://tex.z-dn.net/?f=sin%3D%5Cdfrac%7Bopposite%7D%7Bhypotenuse%7D%5Cto%5Csin%20C%3D%5Cdfrac%7BAB%7D%7BAC%7D%5C%5C%5C%5C%5Ctext%7BWe%20have%7D%5C%20AB%3D25%2C%5C%20AC%3D65.%5C%20%5Ctext%7BSubstitute%3A%7D%5C%5C%5C%5C%5Csin%20C%3D%5Cdfrac%7B25%7D%7B65%7D%3D%5Cdfrac%7B25%3A5%7D%7B65%3A5%7D%3D%5Cdfrac%7B5%7D%7B13%7D)
