Help please triangles and trig
Oksanka [162]

Answer:

\sin L = \frac{3}{5}

\tan N = \frac{4}{3}

\cos L = \frac{4}{5}

\sin N = \frac{4}{5}

Step-by-step explanation:

Given

The above triangle

First, we calculate the length LM using Pythagoras theorem.

LN^2 = LM^2 + MN^2

10^2 = LM^2 + 6^2

100 = LM^2 + 36

Collect like terms

LM^2 = 100 - 36

LM^2 = 64

Take positive square root

LM=8

Solving (a): Sin L

\sin L = \frac{Opposite}{Hypotenuse}

\sin L = \frac{MN}{LN}

\sin L = \frac{6}{10}

Simplify

\sin L = \frac{3}{5}

Solving (b): tan N

\tan N = \frac{Opposite}{Adjacent}

\tan N = \frac{LM}{MN}

\tan N = \frac{8}{6}

Simplify

\tan N = \frac{4}{3}

Solving (c): cos L

This calculated as:

\cos L = \frac{Adjacent}{Hypotenuse}

\cos L = \frac{LM}{LN}

\cos L = \frac{8}{10}

Simplify

\cos L = \frac{4}{5}

Solving (d): sin N

This is calculated using:

If a + b = 90

Then: \sin a = \cos b

So:

\sin N = \cos L

\sin N = \frac{4}{5}
