What is the sign for 90 degrees for angles?
The sign for a 90 degree is a small, perpendicular mark in the corner of the angle, to form a box with the angle.Also, the sine of 90 degrees is 1
Real life example of a straight angle?
The angle between the part of the street before the STOP sign and the part of the street after the STOP sign is usually a straight angle.
What is the full form of sign functoin?
sign function is math matrix function
Is costheta is a vector?
No. Cos theta (Cos θ) is a trigonometric function. A vector is any physical quantity which has both magnitude and direction. For example, Displacement. Displacement has a magnitude like 240m or 0 or 13 m, etc. It also depends on the direction. If an object moves along the positive direction of x-axis, then the displacement will have a positive sign and if it moves along the negative direction of x-axis, then displacement will be negative. Thus, it has both direction and magnitude and so is a vector. Cos theta is a trigonometric function, strictly speaking.

If the terminal side of an angle beta is in quadrant III what is the sign of each of the trigonometric function value of beta?
Tangent and cotangent positive; other 4 negative.
How can 0 and 90 degrees be angles for trigonometric functions even though a right-angled triangle can never have them as 1 of its other angles?
Trigonometric functions take, as input, an angle between 0 and 360 degrees, or 0 and 2 pi radians. While it is useful to think of a right triangle on a unit circle, it is more correct to think in polar coordinates, where r=1 and theta equals the angle in question. The cosine and sign function still remain as the x and y values of the point on the unit circle. Even if you remain in rectangular coordinates, there is no problem, as you simply consider that, at 0, 90, 180, 270, and 360 degrees, the right triangle degrades to a straight line of length one.

Everyday examples of acute angles?
An acute angle is an angle that is less than 90 degrees. The tip of a sharpened pencil is a very narrow acute angle. There are acute angles on a triangular yield sign. The tip of a football is an acute angle.
What is the measure of an interior angle of a stop sign?
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 135 degrees
What is the reference angle for -140 degrees?
in order to find the reference angle, an angle less than or equal to 90 degrees formed by the x-axis and the terminal side of an angle, one needs to first find what quadrant on the coordinate plane the angle belongs to. The negative (-) sign in -140 refers to the direction 360 degree turn begins at (and therefore the quadrant it begins at). Instead of taking the regular backwards "C", counterclockwise direction, the turn begins clockwise. To convert it, simply add 360 degrees, to get 220 degrees, an angle in the third quadrant. These are the guidelines to follow when finding reference angles: If angle, A, is in first quadrant then the reference angle will be itself as it is already 90 degrees or under. If angle, A, is in second quadrant then the reference angle will be 180 - A . If angle, A, is in third quadrant then the reference angle will be A - 180 . If angle, A, is in fourth quadrant then the reference angle will be 360 - A " These subtractions are all in reference to the nearest angle of a quadrant and are in degrees. Being in the third quadrant, take the angle, A, and subtract 180 from it to get: 220 - 180 = 40 Thus, the reference angle for -140 degrees is 40 degrees. Follow the same directions for other angles, first determining whether the angle needs to be converted into a positive value (counterclockwise), then locate the quadrant and use the rules above for the specific angle(s) being looked at and asked for.
What traffic sign is an obtuse angle?
American "STOP" sign (135° inner angle).
Jose measures a regular traffic sign and finds it has an interior angle measure of 135 degrees How many sides does the traffic sign have?
8 sides 180-135 = 45 360/45 = 8 sides

What is Bearings in Mathematics?
in maths we can measure angles using bearings. the angle is always measured from north to the given line so you have to start by drawing a vertical line up from the point you're asked to do the calculation on. then you measure the angle from the north line you've drawn to the line you have. you should give your answer as 3 numbers, followed by the degrees sign so you might need a 0 at the front e.g. if it's only 45 degrees it will be 045 *degrees sign. hard to answer with no pictures or symbols!! .
