The percent change is 10 percent
Answer:
The cotangent of the angle will be b/a
Step-by-step explanation:
Since the cotangent and tangent are reciprocals of each other and the tangent of the same angle is a/b where a and b are not zero,
then the cotangent will be the reciprocal of the value of the tangent
= 1 / (a/b)
= 1 x (b/a)
= b/a
