m∠L=
°

Answer 1

Answer:

Step-by-step explanation:

Adjacent side = 18

Hypotenuse = 60

Those two together form the Cosine.

Cos(L) = adjacent / hypotenuse

Cos(L) = 18 / 60

Cos(L) = 0.3

Now you need to use the inverse Cos Function on your calculator to get <L

<L = cos-1(0.3)

<L = 72.54

Answer 2

$\\ \rm\Rrightarrow cos\theta=\dfrac{Base}{Hypotenuse}$

$\\ \rm\Rrightarrow cosL=\dfrac{LM}{LN}$

$\\ \rm\Rrightarrow cosL=\dfrac{18}{60}$

$\\ \rm\Rrightarrow cosL=\dfrac{3}{10}$

$\\ \rm\Rrightarrow cosL=0.3$

$\\ \rm\Rrightarrow L=cos^{-1}(0.3)$

$\\ \rm\Rrightarrow L=72.54°$
