Question

In ΔLMN, the measure of ∠N=90°, NL = 6.8 feet, and LM = 9.4 feet. Find the measure of ∠L to the nearest tenth of a degree.

Answer 1

43.7

Explanation:

SOH-CAH-TOA

cosL= adjacent/hypotenuse=6.8/9.4

cosL=6.8/9.4

L=
`cos^(-1)`(6.8/9.4)

L=43.6637≈43.
`7^(o\\)`

​

Answer 2

L=43.6637≈43.7∘
