Respuesta :

I got m∠L=72.54 since arccos(18/60)= 72.5423968763.

Answer:

[tex]m<L=72.54\°[/tex]

Step-by-step explanation:

we know that

In the right triangle LMN

[tex]cos(L\°)=\frac{LM}{LN}[/tex] -----> adjacent side to angle L divided by the hypotenuse

substitute the values

[tex]cos(L\°)=\frac{18}{60}[/tex]

[tex](m<L)=arccos(\frac{18}{60})=72.54\°[/tex]
