What is the measure of ∠L?



Enter your answer in the box. Round only your final answer to the nearest hundredth.

m∠L=
°

Answer 1

`\\ \rm\Rrightarrow cos\theta=(Base)/(Hypotenuse)`

`\\ \rm\Rrightarrow cosL=(LM)/(LN)`

`\\ \rm\Rrightarrow cosL=(18)/(60)`

`\\ \rm\Rrightarrow cosL=(3)/(10)`

`\\ \rm\Rrightarrow cosL=0.3`

`\\ \rm\Rrightarrow L=cos^(-1)(0.3)`

`\\ \rm\Rrightarrow L=72.54°`

Answer 2

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
