25 divided by 5 is 5, 45 divided by 9 is 5
Answer:
n=6, m=6√3
Step-by-step explanation:
n = Opposite leg = sin(30°)*hypotenuse = (1/2)*12 =6
m= adjacent leg = cos(30°)*hypotenuse =((√3)/2)*12=6√3
![x=-5\\\\|(-5)-7| = \\(-5)-7=-12\\\\Therefore, \\\boxed{|(-5)-7|=12}](https://tex.z-dn.net/?f=x%3D-5%5C%5C%5C%5C%7C%28-5%29-7%7C%20%3D%20%5C%5C%28-5%29-7%3D-12%5C%5C%5C%5CTherefore%2C%20%5C%5C%5Cboxed%7B%7C%28-5%29-7%7C%3D12%7D)
