An acute angle has less than 90 degrees, an obtuse angle has greater than 90 degree but less than 180 degrees. A reflex angle has greater than 180 degrees.When in doubt, google image search.
The sine and cosine of acute angles are equal only for 45° sin45° = cos 45° = 1/sqrt(2) = 0.7071
It is an obtuse triangle having 1 obtuse angle and 2 different acute angles Or it is an isosceles triangle having 1 obtuse angle and 2 equal acute angles
There are 4 components of angles and they are:- 1 Acute angle which is greater than 0 but less than 90 degrees 2 Right angle which is 90 degrees 3 Obtuse angle which is greater than 90 but less than 180 degrees 4 Reflex angle which is greater than 180 but less than 360 degrees
Well, honey, to draw a quadrilateral with 1 reflex, 1 obtuse, and 2 acute angles, you'll need to start by sketching a shape with 1 angle greater than 180 degrees (that's your reflex angle), 1 angle greater than 90 degrees (that's your obtuse angle), and 2 angles less than 90 degrees (those are your acute angles). Just make sure all the angles add up to 360 degrees, and you'll have yourself a sassy quadrilateral!
No angle has a sine function greater than 1.
Well, the easiest way to go at it is simply to remember thatthe sine and cosine of any angle are always less than 1 .
no - nor less than minus 1.
The sine function outputs values between -1 and 1 for all angles. As the angle of a right triangle approaches 90 degrees, the length of the opposite side relative to the hypotenuse also approaches the length of the hypotenuse, which is the limit when sine = 1. Any angle below 90 degrees will have a ratio of opposite/hypotenuse less than or equal to 1.
1 acute angle = 1 acute angle
An acute angle because it's greater than 0 but less than 90 degrees
The sine of an angle x is defined as the ratio of the opposing side to the hypotenuse, in a right triangle having x as one of its acute angles. If it was greater than 1, it would mean the opposing side was longer than the hypotenuse. Try to draw a right triangle with one of the sides longer than the diagonal. You'll notice it's impossible. So the sine cannot be greater than 1. Fitting the triangle into a circle of radius 1, such that the angle x is located at the origin and the hypotenuse is a radius of the circle, you can define "sine of x" for any angle. Since the triangle may end up flipped in any direction, including the negative x and y axis, it turns out that the sine of any number is between -1 and +1. The cosine is simply the sine of the complementary angle (90 - x). So it must also be contained between -1 and +1.
An acute angle has less than 90 degrees, an obtuse angle has greater than 90 degree but less than 180 degrees. A reflex angle has greater than 180 degrees.When in doubt, google image search.
It is 1.
If you look at the definition of the sine function in a triangle, you'll discover that the maximum possible value of the sine function is ' 1 ' and the minimum possible value is ' -1 '. There's no angle that can have a sine greater than ' 1 ' or less than ' -1 '. So the absolute value of the sine of anything is always ' 1 ' or less.
If you mean the sine function, it is dependent on an angle. For example, the sine of an angle of zero degrees is zero; the sine of an angle of 90 degrees is one; for an angle of 180 degrees, the sine is again 0; if you make a graph, you get a curve that looks like a wave. In general, the values the sine function can take are between 1 and -1, inclusive.
