Answer:
[tex] \frac{24}{25} [/tex]
Step-by-step explanation:
using the cosine ratio;
[tex] \cos(\theta)= \frac{adjacent}{hypotenuse} [/tex]
From the question, the side of the right angle triangle that is adjacent to the measured <a,(i.e BAC) is AC=24 and the hypotenuse is AB=25
This implies that,
[tex]cos(a)= \frac{24}{25} [/tex]
