an acute angle
An angle of 25 degrees is an acute angle because it is greater than 0 but less than 90 degrees.
90 - 25 = 65. The answer is 65 degrees.
Multiply the speed by the cosine of the angle (25 degrees in this case). For the vertical velocity, multiply by the sine of 25 degrees.Multiply the speed by the cosine of the angle (25 degrees in this case).

Exterior angle of a regular 25-gon = 360/25 = 14.4 degrees. So interior angle = 180-14.4 = 165.6 degrees.
