A:
Answer:[tex]CosC=0.882[/tex]Step-by-step explanation:From the figure, it is given that ABC is a right angled triangle such that AB=24, BC=45 and AC=51.Now, as we know that the value of CosC is given as:[tex]CosC=\frac{Base}{Hypotenuse}[/tex]From the figure, the value of Base is =BC=45 and hypotenuse is=AC=51, therefore:[tex]CosC=\frac{BC}{AC}[/tex][tex]CosC=\frac{45}{51}[/tex][tex]CosC=0.882[/tex]Thus, the value of CosC is 0.882.
