First, I assume the question refers to tan(90 degrees) not Ten90' because (apart from the incorrect spelling of tan) 90' represents 90 minutes or 90/60 degrees = 1.5 degrees. The tangent of an angle is defined as the ratio of sine to cosine of the angle. When that angle is 90 degrees, the cosine is zero and so calculation of tan involves division by 0. And, in mathematics division by 0 is not infinity - it is not defined. So, tan(90) is NOT infinity. It is not defined. tan90 has a positive asymptote when you approach 90 degrees from below but has a negative asymptote when you approach from above.
The answer is 60 and 240 degrees. Add radical 3 and inverse tan to get answer add 180 for other answer less than 360.
The last angle would have to be 60 degrees as well. Since there are 180 degrees in a triangle, 60+60=120 and 180-120=60, it has to be 60 degrees.
tan(-60 degrees) = - sqrt(3)
1.732

The exact value of 60 degrees would be 1/2. This is a math problem.
tan(pi/3) = tan (60 degrees) = 1.732 which is square root of 3
B: -tan(25)
Tan 42 degrees = 0.9004
tan(11o) = 0.19438 =======
The y component of velocity can be found using trigonometry. Since the angle is 60 degrees, the formula to calculate the y component of velocity is: y component = x component * tan(angle). Given the x component of velocity as 5 m/s and the angle of 60 degrees, the y component of velocity is approximately 8.66 m/s.
tan(22.5)=0.414213562
The answer is 0.2867.
