Question

express cos i as a fraction in simplest terms.
answer
attempt 1 out of 3
cos i =

Explanation:

Step1: Recall the cosine formula

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

Step2: Identify the adjacent side and hypotenuse for angle $I$

For angle $I$, the adjacent side is $I$H ($23$) and the hypotenuse is $I$G ($25$).
So, $\cos I=\frac{23}{25}$.

Answer:

$\frac{23}{25}$
