i cant read the scribble

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

i assume it a rt tri?

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

its 72 degrees

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

72 degress = 72pi/180 radians

so what would it be?

do you know how to use a calculator?

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