Question

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

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

Answer 2

`m<L=72.54\°`

Explanation:

we know that

In the right triangle LMN

`cos(L\°)=(LM)/(LN)` -----> adjacent side to angle L divided by the hypotenuse

substitute the values

`cos(L\°)=(18)/(60)`

`(m<L)=arccos((18)/(60))=72.54\°`
