Durante cuantos dias se presto un capital de 56000 al 15% trimestral para que produzca un monto de 57680

Step-by-step explanation:

you need to learn English cuz like who even cares anymore

Given that sin A=0.725 is an acute angle in a right angled triangle we are required to find cos A
sin A=opposite/hypotenuse
sin A=0.725=29/40
this implies that
opposite=29
hypotenuse=40
using the Pythagorean theorem we can calculate the adjacent hence the cosine function
c^2=a^2+b^2
thus
40^2=29^2+b^2
b^2=40^2-29^2
b^2=759
b=sqrt759
b=27.54995436~27.55
hence 
cos A=27.55/40=0.68875
