Determine the exact values of the six trigonometric functions of the real number t

now, keep in mind that, the hypotenuse is just the radius unit, so is never negative, so if the cosine is negative, that simply means it has to be the numerator, the 8 is negative, -8. that means



so, the adjacent is -8, the opposite side is 15, and the hypotenuse is 17, so just plug them in then

Ihonestly don’t no that
