it has to do with the arccos of the angle

The side length is 176 and the degrees is 72 inside the triangle

then cos(72) = s/176 176 cos(72) = s you justs got to remember your definitions on your trigs

The question is what is the missing side length based on that information

make sure your calc is on degrees and not radians; or simply substitute 72 with, 72pi/180

yes, but calculators can be set to read degrees or radians; 72 degress is NOT 72 radians

72 degress = 72pi/180 radians

Ok then that.. how would you solve it? Cause im like they only gave me the angle degrees and a side length and are asking for the other side length

the point being: the side length is determined by the cosine function cos = side/hypot cos(72) = s/176 ; multiply both sides by 176 176 cos(72) = s

if not, the wolf will give an approximate value; otherwise, that is the exact value
