Question

use triangle ltf to answer questions 4 - 6.

1. what is cos f?

your answer i

Explanation:

Step1: Recall the cosine formula

In a right - triangle, $\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}$.

Step2: Identify sides for angle \(F\)

For angle \(F\), the adjacent side is \(FT = 6\mathrm{cm}\) and the hypotenuse is \(LF=10\mathrm{cm}\).

Step3: Calculate \(\cos F\)

Using the formula \(\cos F=\frac{FT}{LF}=\frac{6}{10}=\frac{3}{5}\).

Answer:

$\frac{3}{5}$
