Answer:
cos a = [tex]\frac{7}{25}[/tex]
Step-by-step explanation:
Given
sin a = [tex]\frac{24}{25}[/tex] = [tex]\frac{opposite}{hypotenuse}[/tex]
tan a = [tex]\frac{24}{7}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
Then this is a right triangle with opposite = 24, adjacent = 7 and hypotenuse = 25 , then
cos a = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{7}{25}[/tex]
