For values to have congruent sin and cos value, it means that sin x=cos y

thus from the given values, the values that sin x is congruent to cos y will be found as follows;

70

sin 70=0.9397

getting the cosine for y values we get:

cos 160=-0.9397

cos 70=0.3420

cos 120=-0.5

cos 20=0.9397

from the above we see that the cosine value congruent to sin 70 is cos 20

thus from the given values, the values that sin x is congruent to cos y will be found as follows;

70

sin 70=0.9397

getting the cosine for y values we get:

cos 160=-0.9397

cos 70=0.3420

cos 120=-0.5

cos 20=0.9397

from the above we see that the cosine value congruent to sin 70 is cos 20
