What does sec 180 equal?
The value of sec 180 degrees is equal to 1 divided by the cosine of 180 degrees. Since the cosine of 180 degrees is -1, sec 180 equals -1. Therefore, sec 180° = -1.
What is the cosine of 90 degrees?
The cosine of 90 degrees is zero.
What is the cosine of 8 degrees?
The cosine of 8 degrees is 0.99026806874157031508377486734485
What is the cosine of 40 degrees?
Cosine is 0.766
What is the cosine of 24?
The cosine of 24 degrees is 0.913
What is the secant of 60 degrees?
The secant of an angle is the reciprocal of the cosine of that angle. For 60 degrees, the cosine is 0.5, so the secant is 1 divided by 0.5. Therefore, the secant of 60 degrees is 2.
What does sec 180 equal?

What is the measure of an angle whose cosine 0.5?
The measure of an angle whose cosine is 0.5 is 60 degrees (or (\frac{\pi}{3}) radians) in the first quadrant. Additionally, in the context of the unit circle, the angle can also be 300 degrees (or (\frac{5\pi}{3}) radians) in the fourth quadrant.
How do you find the angles of an acute triangle?
Measure two of them. Then the third is 180 degrees minus the two that you know. Or measure the lengths of the sides and use the cosine rule.
What is cos42?
Cosine(42 radians) = -0.399985 Cosine(42 degrees) = 0.743146
What is cos84?
Cosine(84 radians) = -0.680023 Cosine(84 degrees) = 0.104528
