if you were to ask me which is the degree measure of an angle whose tangent is 5.67, I would tell you that it is a degree of 45. I would also tell you that it is a degree of 63 and a degree of 75.

## Answer choice C: 63 degree

Suppose we have a triangular bed, and the two sides are 40 m and 60 m. The angle between the two sides is 22deg. The shortest distance from point C to side c is 6.9 miles. The answer to this problem is the answer choice C: 63 degree of an angle whose tangent is 5.67.

The tangent of an angle is defined as the shortest distance from a point to a side that is in a right angle to the other side. The tangent of an angle is not defined when the angle is 90 deg plus 180 degrees. The tangent can be calculated with the half angle formula or by dividing the sine by the cosine. If the tangent is not calculated, multiply the top and the bottom by two. Then subtract the resulting sum from the total length of the shortest distance. The result will be positive.

This question was answered correctly by the student. The student’s answer was C: 63 degree of an angle whose tangent is 5.67.
