The greek letter theta is usually used to denote an unknown angle. An angle of 90 degrees is a right angle, an angle between 0-90 degrees is an acute angle, bigger than 90 degrees but less than 180 is an obtuse angle, and bigger than 180 but less than 360 is a reflex angle.
Feet are usually written as ', and the symbol is also used to denote arcminutes. Prime units of any type will also be marked in such a manner, as are minutes of angle and time.
Let's denote the measure of the angle as x degrees. The complementary angle would then be 90 - x degrees. According to the given information, we have the equation x = 14(90 - x). Solving this equation, we find x = 70 degrees and the complementary angle is 20 degrees.
Let s denote distance v denote speed t denote time. s = integral(v)dt If speed is constant, s = vt.
