Respuesta :

Answer:

sin a=3/5

cos a=4/5

Step-by-step explanation:

sin A

AB(squared)=AC (squared)+CB(squared) AB(squared)=4(squared)+3(squared)

AB (squared)=16+9

AB (you must put a square root over AB)=25(remember 25 is now a square root)

AB=5

sin a=opposite/hypotenuse

=3/5

cos A

cos a=adjacent/hypotenuse

=4/5
